It’s best to handle your collectible coins as little as possible. A coins' quality and value decline when scratched, dusty, damaged by moisture or when fingerprints are present. If you simply have to handle your collectible coins, only touch the outer edges of the coin to minimize contact with your hands.

Coin cleaning, which is not recommended, should be handled by a specialist. In fact, the patina developed on a coin over time may actually be a desirable quality to collectors and a cleaned coin could actually decrease it's potential value.

Even though most holders offer plenty of safeguards against fingerprints and dust, you want to be sure that your really rare quarters are protected from moisture as well. 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.
