Caring for Coins
To retain the value and look of your coin collection, proper care and storing is essential.
Cleaning
While you may be tempted to clean your coins to make them look shiny and new, proceed with caution. Most of the time, cleaning coins reduces their value. Believe it or not, older coins that show the deep coloration of age are far more desirable than coins whose surfaces have been stripped away by improper cleaning.
If you absolutely must clean a coin to remove dirt, use good-quality mild soap and water. Once you've washed the coin, pat it dry with a soft towel. Don't brush or rub it, which can scratch the coin's delicate surface.
Handling Your Collection
To preserve the value and natural condition of your coins, it is important that you handle them carefully.
