Many people make the decision to collect coins and create an investment for their future. Since coins are so small, you don't need a ton of room to store your collection. They also don't require a lot of maintenance like some of the other items people choose to collect. However, you don't want to end up doing anything that is going to destroy your collection either. To keep your collection in pristine condition and prevent any damage to your coins, avoid doing one of the following things.
Touching your coins.
While it is only natural to want to be able to touch your coins, your hands are loaded with oils that you don't even realize are there. Those oils can end up smudging your coins and leaving marks on them. Those marks can destroy the finish and cause all sorts of problems with the coins. Collectors don't want a bunch of smudge marks on the coins. The best way to prevent that from happening is to handle the coins with a pair of soft cotton gloves. This will protect the coins and prevent your oils from transferring over to them.
Attempting to clean your coins.
If you notice your coins are a little dirty, you don't want to try and clean them. As much as it might be a natural instinct to do so and you think you are helping, you are actually going to end up making matters worse. It is better to have a coin that has natural markings on it than it is to try and clean it and take off its natural finish. Coins should be kept inside of a secure package and left there to prevent additional dirt from accumulating on them.
Not storing them properly.
Ancient coins need to be stored properly to prevent them from showing signs of aging. They make secure coin holders that you can slide your coin in and secure it in place for quite some time. This protects it from the elements and allows you to store them easily away. Whatever you do, don't store your coins in a shoebox or other box that isn't protected. They will rub against one another and damage each other in the process.
Coins have to be handled with care and stored properly to prevent additional problems from occurring and costing you money on your investment. Discuss any questions you have with a licensed dealer (like Harlan J. Berk, LTD).
