Taking Care of Collectible Coins
Many collectible coins are made of copper and a collector may encounter problems in maintaining their features and appearance. A person collecting this type of coin should learn how to maintain and take proper care of these expensive collections. Copper coins should be cleaned correctly and must be preserved the same way professional collectors treat their coins.
Professional collectors clean their coins by the process of placing the coins in a container that is airtight. This is a safe way to preserve the features of the coins. Because of the coins’ years of circulation, there is the possibility of a coin accumulating encrustations, coatings, dirt, and other problems on a coin’s face. These accumulations may cause pitting and corrosion to the surface of the copper coin. The corroded portions should be removed properly without making any scratches.
There are products available that are made especially for coin cleaning. Coin suppliers have these products that are specifically made for coin maintenance and cleaning in stock. One product made for this purpose is MS70 which removes corrosion and other surface dirt. It is advisable to use rubber gloves for the protection of your hands, as MS70 can dry the skin but this should be of little concern because it is not that harsh on the skin. A soft toothbrush may help with cleaning and removing any dirt that is in the surface of the coin. Improvement in the appearance of the coin will be seen after it has been soaked and cleaned. If satisfaction is not met on the cleanliness and appearance of the coin, he may add baking soda to neutralize the MS70 and soak it in warm water.
After he is through with the soaking, he may dry the coin using a Blue Ribbon coin cleaner and preservative; he may apply a coat and dry it for a couple of days then wipe the damp parts with soft cotton balls and place it on a small cardboard with a space on the center.
If he finds discoloring on the coin, he may use Dellars Darkener after he has soaked it in MS70. He may use this product before he applies the Blue Ribbon cleaner and preservative until he is satisfied with the cleanliness of his coin. Once satisfied with the new appearance of the coin, he may again return it to its set or collection
