The less you handle your coins the better. Dust, scratches, fingerprints and moisture will affect the quality of your coins and depreciate their value. Direct contact with your collection should be avoided, especially with coins in mint condition, but if you have to touch please do so by only holding the outer edge.

It is not recommended that you clean your coins, but if you do, you should be sure to entrust the process to a specialist. Since collectors might seek coins with the patina of time, cleaning a coin could make it less valuable.

Moisture can cause problems just like fingerprints and dust can, so even though most holders are sufficient to protect your presidential dollars make sure your most valuable pieces are really protected. There are other protectors in the market that can do a better job and guard against moisture than the typical stapled or taped packets, which don’t provide the maximum protection. Protecting your collectible coins from water damage is paramount; choose a dry, controlled-temperature space, never a damp basement or cellar.
