Where to Sell & Refine Dental X-Ray Film

12-8-11    Posted by: clientadmin

Do you know of a place to sell silver from dental x-rays? From Denny in Panama City, Florida

Hi Denny!

You have come to the right place! We have the capabilities to handle large shipments of x-ray film here at our refining facility in Mexico, Missouri including those from dental offices.

Here are the bullet point things to keep in mind. And we have also included some of our past blog articles about selling x-ray film:

  • Quantity: You will need to send at least 300-400 pounds of X-ray film, removed from the paper jackets, to receive a payment and recover the shipping cost.
  • Shipping: We would recommend filling one or two 50 gallon drums of X-ray film and then shipping the film in the drums.
  • Sorting: We can help sort and purge x-rays in eight states including Alabama, Northern Florida, Illinois, Iowa, Kansas, Missouri, Oklahoma and Tennessee. Which would include Panama City if you have enough material to need the service.

We currently work with eight of the top 100 hospital groups in the country and are able to process large amounts of film with quick turnaround time. Please inquire further either by phone or on our contact forms as to the amount of x-rays you have and needed services dealing with selling dental x-ray film.

Sell Gold Jewelry Scrap & Sterling Silver

11-29-11    Posted by: clientadmin

I have about 12 ounces of jewelry scrap from about 60 years ago. I think it might be gold but have not gotten a definitive answer yet. Can I send you some samples? I also have 5 to 10 pounds of old sterling silver and would like to know its value (buckles, money clips, pins, etc.) Can you also let me know if you would be interested in buying it? Thanks. From Mary in Rochester, New York

Hi Mary,

Thank you for your question. Sounds like you are doing some cleaning which could result in some extra cash for you, which is always a plus.

Since you are unsure about the purity of your gold items, we would test your pieces, refine gold that is9 karat purity (37.44% gold) or more and then either send back what is not able to refine or we could recycle it for you. If you have specific instructions for us, please indicate those on our packaging slip.

5-10 pounds of sterling silver is a large range. If your pieces are pure sterling silver, 92.5% silver, at a $35 silver price, 5 pounds of sterling silver could be worth over $2,000 silver value.  Arch would be able to pay 75% of the silver value back to you on your pieces. However, if not all of your pieces are sterling, we would recommend sorting the items you know are sterling and then check to see if your other pieces are sterling or not.

It may be better to send all of your pieces together, but would help if you kept the gold separated from the silver in different bags.

Hope that helps! Let us know if you have any more questions. Or you can upload an image to show up on our Contact Form.

What is the Gold Value of 14 Milligrams Pure Gold?

8-5-11    Posted by: clientadmin

What is 14 milligrams (mg) of gold worth? I am considering purchasing some Buffalo tribute coins that are clad in 14 mgs of pure 24 kt. Gold and want to know what this gold is worth. Thanks from Julie in Chicago, Illinois.
Hi Julie,

Gold is measured in troy ounces. When you see the daily price of gold, you are mostly likely seeing the price per troy ounce. This can be confusing when you are working with other units of measurement.

Here are some quick conversions to give you an idea about how much a troy ounce is in comparison to other units of measurement.

1 gram = 0.0321507466 troy ounces
1 milligram = 0.001 grams
1 milligram = 0.0000321507465686 troy ounces

14 milligrams = .0004494 troy ounces

Now that we have done the correct conversion, let’s talk money! Today (8-3-2011) the price of gold is at $1,637.50 USD per troy ounce.*

1 troy ounce of pure gold = $1,637.50 USD*
1 gram of pure gold = $52.65*
1 milligram of pure gold = $0.05*

14 milligrams of pure gold = $0.74*

As you can tell, 14 milligrams of gold is small. Plus these coins are clad (or covered) in gold and not made from solid gold, so it is not like we could even refine this small amout of gold from these tribute coins.

See more information on the Gold Buffalo Nickel Tribute Proof.

*Prices given reflect the price of gold when this blog post was written. Gold price may or may not be the actual current price of gold.




What is the value of a $50 2011 Buffalo Gold Tribute Coin?

8-5-11    Posted by: clientadmin

What is the value of the Gold Buffalo Nickel Proof by National Collector’s Mint? From Dan in St. Louis Gold Buffalo Coin

In order to comment on your questions, we reviewed the company’s commercial on their website and uses some terminology that is confusing people.

Please read our translation of this TV advertisement. You have to “read between the lines” of the commercial and catch all of the important bits of information.

Advertisement Translation
2011 $50 Gold Buffalo Tribute Proof Obviously, this coin does NOT have a face value of $50.00. It is a tribute proof coin that has no face value. They are a novelty only and that is why they can sell them for under $10.
Description of ORIGNIAL Gold Coin “America’s purist gold coin ever. It was the first one ever struck using .9999 pure 24K gold” … “Price of the original edition is going through the roof.”

They are describing the ORIGINAL coin. NOT the replica they are selling.

This coin is only a COPY of the original. It even has the word “Copy” printed on the coin.

Clad in 14 mgs. Of Pure 24 KT Gold

1) Clad means that it is only plated with gold and is made mostly of some other metal

2) 14 mgs. is worth is about $0.50 to $0.75 cents of gold value.

Read more about the value of 14 mgs of gold on our previous blog post.

Distributed by the National Collector’s Mint Despite the official sounding name, this is a private company. It is NOT an official US government mint. They make replicas
“With gold skyrocketing past $1,300 an ounce, price can only be guaranteed for 7 days.” This is an area that could cause confusion as it implies that the market price of gold has an effect on the value of this coin. The reality is that the amount (14 mgs) of gold is so small that a change in the price of gold by $100 would only affect this coins gold value by 4.5 cents.

The bottom line is that these tribute gold buffalo coins that you see advertised on TV have no gold value. People wishing to invest in gold should not buy these coins. Think of them more like commemorative spoons or plates.




Refining Silver Electrical Contacts

6-13-11    Posted by: clientadmin

What is a good place to sell silver electrical contacts? Do you all do this? How much silver is in electrical contacts? Thanks! From Dan in Waterford, Michigan

Hi Dan,

Thanks for contacting us!

You will be happy to know that you have come to the right place. We can refine silver electrical contacts. In our experience of refining electrical contacts made from tungsten silver, they can contain between 25-30 percent silver.

Silver Electrical Contacts

Refining this type of material is ideal because of the significant amount of silver to extract. How much of the silver material do you have? We can help arrange freight if you have a very large shipment.

Find out more information about electrical contact from relating blog posts here:

Refine & Sell Sterling Silver Belt Buckles

5-23-11    Posted by: clientadmin

I have a collection of sterling silver belt buckles. I bought them based on being sterling. Some of them have gold and are marked, e.g., 22k Gold on Sterling, 1/10 10k Gold on Sterling and so on. How can I tell the value of the gold parts? Thanks, Rod from Cleveland, Ohio.

Hi Rod,

Thanks for your question! The markings on your sterling silver belt buckles indicate the purity of gold and silver used to manufacture the items. However, it does not tell us how much gold would be available, if any to recover.

Most of the time we are not able to refine any of the gold from these belt buckles you have described, because the amount is so small. If you cannot physically separate the gold from the silver before the melting process begins, then there is no way to recover the gold from the silver.

Sterling Silver Belt Buckle

Also the marking 22k gold on sterling sounds like they used a 22k gold plating material over top of a part of the buckle. Like we say to people with gold plated silverware, the plating technology has advanced to the point where the gold cannot be recovered and separated from the silver during the refining process.

If you can separate the gold from the silver before you ship, then we would run tests to determine the purity of the gold and the silver, then refine and melt them with separate refining methods.

You can go to our website to learn more about the ideal types of silver to refine. Hope that helps!

Sell and Refine Silver Oxide Watch Batteries| Precious Metal Refining Blog

3-22-11    Posted by: clientadmin

I have a large amount of silver oxide watch batteries that I would like to have refined for the silver. We are talking several hundred pounds of this material. Can you give me a price per troy ounce or price per pound? From Jim in Houston, Texas

Hi Jim,

Silver has been in the headlines as the price has reached $36 USD per troy ounce for the first time in 30 years. So now it a great time to have silver oxide batteries you have refined. When you say “several hundred pounds” are you sure that they are all silver oxide batteries?

Silver Oxide Batteries

Other batteries that may look like silver oxides are lithium or alkaline batteries, that are not manufactured with silver at all. Though it is still a good idea to recycle these batteries in an environmentally friendly manner so the toxic contents of the batteries do not leak out into the earth, we will not be able to offer a return on non-silver batteries.

It saves us time and money if you have already sorted your batteries. However, if you have a comingled lot we can discuss our sorting fee if you would like. Also because you have such a large amount, we can quote special pricing for you.




How to Sell Your Precious Metal Items

11-4-10    Posted by: clientadmin

1) Have reasonable expectations. Unless you know for a fact that you have valuable precious metal items, be prepared that there may be very little precious metal available for extraction. Also keep in mind that a refiner’s offer only reflects the value of the item by weight and quantity alone, not the retail value.

2) Do your homework. So you are not surprised, try to assess how much your items are worth beforehand. This could include several steps such as researching precious metals online, making a trip to a local jeweler or requesting an online estimate. Also, remember to remove stones and any other non-metal materials before sending them to the refiners.

3) When you’re ready to sell, research a dealer you are comfortable with. There are many gold buying scams out there that you want to stay away from. Here are some tips to avoid being taken advantage of:

  • Determine if the dealer is a middleman or the refiner. A middleman will buy your items for less in order to resell to a refiner and turn a profit. Refiners have more knowledge of the actual process and can offer a better price than a middleman. Arch Enterprises is a refiner and offers between 60%-90% of the metal value to sellers.
  • Look for creditability through who endorses the company. If reputable companies stand by a refiner, this reflects positivity on their business dealings. Arch Enterprises is endorsed by the Missouri Dental Association and the Kansas Dental Association.

4) Insure your items through the mail. Make a note of what you’re sending off by writing descriptions, taking pictures or both.

5) Be organized. Cover all your bases by making copies of all the documents you send and receive to keep for your records, including emails. Even record all phone calls with the date, time and information discussed.

6) If you have a positive experience selling your precious metals, tell others and spread the word.

Send Medical X-Ray Film to a Refiner | Precious Metal Refining Blog

10-21-10    Posted by: clientadmin

I have about 320 pounds of X-ray film. Do you pay per individual X-ray or per pound? From Jim in Chester, Virginia

Hi Jim,

Because we refine X-ray film by the truckload it would be nearly impossible to keep an accurate count of individual X-rays. The amount of silver in one X-ray is negligible. We pay per pound of X-ray film because it is more accurate and easier for us to track.

The amount returned can add up if you have large quantities of X-ray film, especially when silver is trading for more than $18 per troy ounce. You will need to send at least 300-400 pounds of X-ray film, removed from the paper jackets, to receive a payment and recover the shipping cost. We would recommend filling one or two 50 gallon drums of X-ray film and then shipping the film in the drums.

Please let us know if you have any more questions and don’t hesitate to give us a call. Thanks!

Convert Scrap Gold into Coins or Bars | Precious Metal Refining Blog

9-16-10    Posted by: clientadmin

Hello, I have been in the rare coin and paper money industry for some time and I have in the past few months started to buy scrap jewelry and other “unwanted” items from people all across Northeastern United States. I was wondering if I could have the scrap gold items melted down by a refining company and receive coins, bars, or a “brick” of the refined metal in return? Thanks so much. – Craig from Hershey, Pennsylvania

Hi Craig,

Because we are a gold refiner and not a gold mint, we typically pay for scrap gold with cash (technically a check…but you get the point). Unfortunately the raw gold generated during the refining process is not marked, stamped or hallmarked.

Given this, we sometimes return payments in the form of silver or gold minted coins or bars instead of cash, but there are additional fees involved. By using minted coins or bars, there will be no questions to the value of your gold or silver and you will be able to hold the items as investments.




The Do’s and Don’ts for Shipping Precious Metal

5-18-10    Posted by: clientadmin

How would you recommend shipping silver and gold material through the mail? From Kara in San Antonio, Texas

Hi Kara,

Shipping precious metal material through the mail does not have to be a daunting process if you follow some general guidelines. You can even cut your shipping expenses by using flat rate shipping boxes which we found are great for sending heavy precious metal items such as silverware that does not take up too much room. Also, for quicker processing you can choose the option to overnight mail packages or express mailing.

What to DO:
DO get a precious metal estimate and decide if you are comfortable or not with insurance and to what degree.
DO request the “Delivery Signature Required” option so you know your items are signed for.
DO weigh your items before you ship.
DO include a packing slip with your shipments.
DO track your shipment with your carrier.

What NOT TO DO:
DO NOT write gold, silver, platinum or any other identifying words on the outside of your shipment.
DO NOT send in silver or gold plated items to precious metal refineries.

We also advise consumers to consider the name of the company they send to. For instance we do not use “gold,” “silver,” or “precious metal” in our name intentionally so no one will know the contents of the package just by looking at whom it is shipping to.

Where to Recycle Bench Sweeps

5-13-10    Posted by: clientadmin

Hi There, I am an independent bench jeweler and ever since my old refiner went out of business, I have nowhere to send my bench sweeps. Do you refine sweeps, and if so, is there a minimum? And what is the approximate turn around time? From Sadie in Columbus, Ohio

Hi Sadie,

We do have the capability to refine and extract precious metal from bench sweeps. Shipment methods will depend on how much material you have. There is no minimum amount, but we would recommend shipping more than 0.25 lbs. Ship by putting all your sweep material into a plastic container with a tight lid or double zipped plastic bags.

Once your materials arrive at our refining facility we will test and refine your materials then return a check to you generally within 3-5 business days. However, sweeps take longer than a typical refining process as we have to test the materials extensively to ensure we extract the maximum precious metal available.

We would recommend trying to keep your sweep material separated while you are collecting it. Working on smooth surfaces might make it easier to collect scrap. Cleaning and separating scrap will be easier if you maintain a clean work station throughout the day. Here are the groups we find easiest and most helpful to maintain:

  1. Fillings, Grindings and Snips
  2. Solids – Chain, Wire, Parts
  3. Polishings and Sweeps
  4. Platinum
  5. Silver – Try and keep gold and silver separated if you can. If this is not possible, send all your materials in combined.

Additionally, we commonly refine precious metal from floor mats, sink traps, carpets, rags, vacuum bags, and towels from jewelers’ working facilities. Visit our website for more information about our refining services for jewelers.




Where to Sell Silver Dollar Coins

4-21-10    Posted by: clientadmin

I have several silver dollar coins that I would like an estimate on. They are as follows:

Year / Number

1923 / 48
1922 / 30
1924 / 10
1925 / 10
1926 / 4
1927 / 3
1800’s / 47

Thanks! From Jordan in Cleveland, Ohio

Hi Jordan,

Thank you for your question. We would be able to pay you for 90% of the fine silver value on your silver dollars that you have described. However, we do not take into account the numismatic or collection value of any coins that we refine. Please send them to us if you know that the actual silver value is more than what you could get if you took them to a coin dealer.

I would especially recommend taking your coins from the 1800’s to a coin dealer to check on their collection value. Even coins that are not in pristine condition can still have collection value that may exceed its silver content value.

Let us know if you would like to refine your silver coins based on their silver content. Thanks!




Jewelry Designer from NY

2-10-10    Posted by: clientadmin

I’m just a humble jewelry designer from NY who is trying to get used to all this stuff! From Natalie in New York, Arkansas

Hi Natalie,

Don’t worry if you don’t pickup on everything right away. It takes sometime to get to know the precious metal industry. Here are some helpful tips that I’ve put together for you and other jewelry designers out there that may have some scrap precious metal to refine.

It’s great that you are learning and researching about this now so you have all the tools at hand. We work with jewelry designers, jewelry sellers and gold party representatives from all over, let us know if you have any questions about precious metal!

Keep in mind that precious metals include: gold, silver, platinum, palladium and rhodium.

Pay attention to where you scrap is going.

From small gold chain links to shavings of silver, try to account for it all. For larger pieces of gold, silver or platinum that you cannot use in creating or fixing jewelry its best to keep them as separated as you can. We recommend working on smooth, dark surfaces so you can see scrap easier.

Don’t throw anything out, it could be precious!

Even your facility that you resize, shape and design jewelry in can contain valuable precious metal scrap. Areas where precious metal can be accumulating include sink traps, floor mats, carpets, rags, floor sweeps and vacuum bags. Think about this when you’re cleaning your facilities. If you regularly clip, size and shape precious metal chances are small pieces of it have gotten away from you. As precious metal refiners we can extract even the smallest amounts of precious metal from these items.

Keep your stones and gems.

As precious metal refiners, we only return payments for metal materials, not stones and gems. To reclaim the value on these items, make sure you remove them before sending them to any metal refinery.




How to Request a Precious Metal Estimate

1-25-10    Posted by: clientadmin

In the last six months we have received some great questions! In order for our customers to receive the best information and most accurate quotes we encourage everyone to give very detailed descriptions of the materials you would like us to buy and refine. Even things that you may not think are significant can indicate what kind of material you have and what the grade is. Here are the main elements we take into account when people ask questions about their materials.

  1. Type of Metal – of course the type of precious metal your items contain is the main indicator of how much they are worth refined.
  2. Markings/Hallmarks – these are especially important on sterling silver sets and flatware. Always try and indicate if these items are marked with the word ‘sterling’, 925 or 800. 925 silver is 92.5% silver, where as 800 silver is only 80.0% silver.
  3. Weight – there is a very big difference between the weight of items before they are refined and then the weight of the actual precious metal contained in items. We try and estimate only on the value of the precious metal content. So account for the fact that 40 lbs. of material is not the same as 40 lbs. of pure silver.
  4. Quantity – the amount of precious metal you have to refine is important because often times we can offer you a higher return on larger amounts of material. This is because it is more energy efficient to process large amounts of material at once than several smaller quantities at different times.

On our Submit Your Question Form, there is an image upload capability where you can send us a photo of the items you wish to refine.

As always, let us know if you have any questions.

Cash for Gold on Good Morning America

1-22-10    Posted by: clientadmin

It seems like many media sources are conducting investigative reports on the cash for gold business. This is due to the many customer complaints about companies such as the one highlighted on Good Morning America this morning – Cash4Gold. Our goal with this blog is to help people become more educated consumers in this industry that historically has not always been the most trustworthy. With these huge operations you really have no idea who is giving you your quote or who is actually melting and refining the material. We recommend getting to know the people you work with either by giving them a call or sending them an email.

The consumer alert from Good Morning America highlighted the fact that some companies will only give 11%-29% of the gold’s value back to their customer. Also that these companies do not want the public educated on the gold buying because they thrive on people’s ignorance towards measurements and value. Here are some things to take into account when choosing a company to work with.

  • Check out the company’s endorsers. If they are a member of the BBB, look at their rating and you can also see if they have had any recent customer complaints.
  • Look to see if they have an actual business location, so they are not some guy working out of his basement. If they don’t look reputable, then chances are they probably are not.
  • Get the on the phone. Because each piece of gold is different, each estimate will be different as well. This will allow you to ask any questions you have, establish a relationship with your dealer and give you an indication of what your customer service will be like.

Good Morning America also commented on gold parties which are becoming more popular. Remember that you don’t have sell your gold to the operator. We recommend getting some estimates either online or locally before you attend. That way you will have some idea of what your material is worth beforehand.

Did anyone else see the Today Show? We would love to hear your comments or questions.

Can you evaluate and process large orders?

1-20-10    Posted by: clientadmin

Do you have a facility in TN? Can you evaluate and process large orders? Do you buy and what is the process and how long does this take? – From Roger in Knoxville, Tennessee

Hi Roger,

We have a representative in the Tennessee area but not a facility. Our facility in Missouri can handle large orders. We can take shipments by the ton. With three thermal oxidation processors and three large-scale R4-B rotary furnaces, there is almost no job involving precious metal too large for us to handle.

For large volumes of material we can work with you directly and arrange shipping and/or transportation. For large orders we like to speak with our customers so we both have a better idea about the job we are dealing with. Then we can more accurately estimate how long it will take to process and what the payout will be. Sometimes it is better to send a sample that we can test before refining. Let us know what kind of material you have, and then we can talk about dollar estimates and times.

Visit our website to find out more about our precious metal refining facility.




Raw Gold Ore Testing from Gold Panning

12-8-09    Posted by: clientadmin

I watch gold fever on the outdoor channel on Saturday morning. If I had the supplies, I think I would try panning myself. I asked the pawn shop if I could bring it there if I found any gold. She said they could test it but didn’t say if she would buy it. Do I deal with a pawn shop or you guys with raw ore like that? Giving 1 oz as an example, and todays prices, how much does testing cost and the net cost after testing? — Sue

Hi Sue!

You can send us samples of the raw ore and we can analyze them for $75-$150 depending on the size of the rock you send us. If we end up refining it we will not charge you the fee for testing. We can return to you a large percentage of gold value after refining but the exact amount will depend on the quality and volume you find.

Be careful when dealing with pawn shops and selling raw gold to them. Because they will most likely sell the gold to a refiner like Arch Enterprises themselves, it’s in your best interest to sell directly to a refiner without middleman pawnshops. Hope this helps, good luck panning.

Thanks!

Refining Silver Flatware and Tableware

7-22-09    Posted by: clientadmin

As one of the largest silver refiners in the U.S., we process thousands of different silver items every year.  One of the most common is silver flatware.  In today’s less formal world, many of you apparently just don’t have a need for that set of sterling you inherited or those silver candlestick holders you got as a wedding gift years ago.  Check out this video where we explain some of the issues related to valuing silver flatware and weighted items.

Arch Enterprises is one of the nation’s leading precious metal refineries. The company is happy to answer questions about precious metal refining for items made from gold, silver or platinum.

Estella in Grand Rapids, MI asks if all silver plated flatware is brass under the silver plate. There are many different kinds of silver plating techniques. Arch only refines sterling silver, however other metals may be able to be recycled and sold.
