Cleaning Coins

Rinse the coins, using distilled water. Avoid using tap water because it contains chemicals that will, over time, erode the coins. The purified water will rinse off any leftover chemicals from the coins. Place the coins on a clean, soft cloth and gently dab them, turning over once to ensure both sides are dry. Coin cleaning is the process of removing undesirable substances from a coin’s surface in order to make it more attractive to potential buyers. The subject is controversial as no consensus exists among the numismatic community whether cleaning is necessary. Those that argue in favor of cleaning are also in dispute on which methods work best. Serious coin collectors do not clean coins, since in most cases, the cleaning job will lessen the coin’s value. Most of the change in your pocket, however, is worth only the amount stamped on it. But cleaning pennies can be an interesting science experiment. Reasons NOT To Clean Coins Say that a coin is in excellent condition, it has full LIBERTY, all fine lines and details are clear, but there is a little tarnish or black junk that shows on the details of the coin I would say DO NOT clean this coin at all. Abrasive cleaning, using a brush and an acid or alcohol solution, can leave the coin with hair lines and discrepancies in the metal that may only be seen under the right lighting and magnification.

It may come as no surprise that coins are some of the dirtiest items you can possibly pick up. After all, just think of all the hands they pass through on an average day, and how many germs and other particles get stuck in their crevices and engravings. Multiply that by years, and the coins in your pocket or your piggy bank are just loaded with dirt and other filth that chips away at their natural allure, deteriorating the surface composition, and ultimately making your coins visually unappealing. In this article, we shall discuss various ways on how to clean coins in bulk.
If this sounds like your coin collection, restoration is possible, even in bulk. If you are looking to clean a large accumulation of regular coins, there are several ways to do that. If, however, you happen to own rare, high-grade, or uncirculated coins, these need to be treated in a special way, ideally by a professional, and any attempt to clean these coins as you would standard coins used for monetary circulation may result in damage or reduction of their value.
I’ve reallystruggled coming up with a good way to clean copper coins like large cents andIndian head pennies. Most of the time you’re not going to hurt the value as ithas already lost all or most of its value from corrosion so I am more interestedin cleaning them up to actually see the detail and get a date from it.
Here is a quick example of how corrosion hurts the value – Years ago I found a stunning 1872 Indian head penny with beautiful detail. It looked like it was dropped the day it was minted besides the green patina that you’re going to find 99% of the time on a dug copper coin.
Curious if there was any value to it with the green patina, I went to three different coin dealers over the course of several weeks to find out. Each one gave me a value somewhere around ten dollars. Not bad for a coin with the face value of one cent, right? Well, if the coin didn’t have that beautiful green patina it would have been worth several hundred dollars!
After finding out how the beautiful green patina effects a coins value I was no longer worried about cleaning copper coins at least to where they are presentable. Often, I find myself cleaning copper coins and copper and brass buttons just so I can see the detail and get dates to show.Coin Cleaning Solution
In the past I have tried several different methods at cleaning copper coins with little to no success. At one time, for really corroded copper coins that I couldn’t even make out detail I would use a product called MS 70. It would literally strip the coin down the bright, shiny copper. Once the coin was stripped then I would use another product called Dellers Darkener that you would rub on the coin until you got the desired darkness you wanted. I will say it worked amazing on the worst of the worse but was entirely to harsh for cleaning dirty copper coins even if they had some corrosion. I know this sounds harsh but one time I found a large cent that I couldn’t get a date to show. A friend suggested tumbling it and even that didn’t make it readable. A few years later, after finding out about MS 70 I decided to try it and follow up with Dellers. Not only could I clearly see the date, you could clearly make out the details! Unfortunately, you can no longer get Dellers Darkener and the formula for MS 70 has changed and will no longer strip a copper coin.
Another method Itried and stuck with was simply picking at the copper coins I was cleaning witha toothpick, once as clean as I could get it, I would simply rub some wax onit. Depending on the condition of the coin this worked with mixed results, butit’s been my method for the last several years Composite Cleaning Pencil
I recently got a composite cleaning pencil from mygood friend Brian Harvey from Diggers Den. A few months back I had GrahamDempsey on the All Metal Mode UK podcast who makes the pencils. He is a fellowdetectorist who has been in composite engineering for almost 30 years. I had totry it!How Do Professionals Clean Coins
The composite cleaning pencil comes with twofilaments. One is used for removing heavy material and the other is forremoving the finer material once you’ve removed the big stuff.
The first coin I used it on was the large cent.Although it wasn’t easy to do, I ended up overcleaning it. I actually removedso much patina that there were bare copper spots. How it happened is you canclearly see the bubbles on the large cent, the coin was so crusty I justthought it was dirt but instead it was where part of the coin bubbled up. Thecoin is pretty well trashed, but it did clean it as good as you could expect atrashed coin to be cleaned.
With more practice and learning to take it slow I’vehad excellent results. The filaments hold up really well and will probably lastme a lifetime. I have heard that some of the other composite cleaning pencilsare known for being messy and the fiberglass splintering and coming apart.Graham Dempsey assured me this would not happen with his and after many coinand buttons cleaned by me, I believe him!
If you’re like me and have a bunch of crusty, nastycopper and brass sitting around that needs cleaned up I say look no further!This is the best thing I’ve ever found for cleaning up even the crustiest ofcoins and the best part it’s chemical free. Not to mention very affordable!Cleaning CoinsRelated Metal Detecting Articles:
