Regardless of what a person collects, sooner or later he will face the problem of storage. Numismatists, in addition to the method of placement, have to take care of the safety of their collection. After all, coins are very sensitive to environmental influences and require constant care.
Storage
If the coins are not stored in special packages, sooner or later this will lead to their damage. Moving the coins will rub against each other, causing scratches and chips on their surface. In addition, from a long exposure to air, metal exhibits will oxidize and darken.
To avoid corrupting your collection instances, you need to store them properly. For these purposes, special accessories are sold. These are sheets, albums, and holders. However, be careful and always study the composition of the product. Unscrupulous manufacturers, in order to reduce the cost of production and to give it a glossy appearance, add polyvinyl chloride to the composition. PVC contributes to the appearance of corrosion on coins, so such sheets and holders are only suitable for temporary storage. In addition, there are no special requirements for storage accessories. You can use special cardboard albums for certain sets of coins, refillable and standard blots, cases, etc.
Care
Numismatists acquire not only new coins in perfect condition. Sometimes they end up with specimens that are deplorable in appearance; exhibits can be dirty, oxidized, discolored and corroded.
You need to clean the items of the collection in several stages. First, dip the coins into a glass of warm, soapy water to soften the surface of the dirt. Then wipe off the dirt with a soft sponge or cloth. This is a surface cleaning method; only gold can be used to remove oxidation with soapy water. To clean silver, you need to know its fineness, if it is less than 625, you can use ammonia. Higher quality coins can be restored to their original form by soaking them in lemon juice.
Some numismatists use GOI paste or chemicals that are used for household purposes, cleaning and cleaning rust to remove strong contaminants. But be careful. Paste can scratch specimens, and liquids leave red spots. True, over time the coins will be covered with patina and the stains will not be noticeable.
If you do not want to risk the state of your collection, use special cleaning products. They are usually sold in coin shops. And use the tools at hand only to remove light dirt. And never rub coins with brushes or embrasures.
