Try to handle your 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.

Cleaning coins is not recommended and should be done only by an expert, and only when absolutely necessary. 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.

Most holders provide adequate protection for seated liberty half dollars but you will want to be sure that your most valuable coins are protected not only from fingerprints and dust, but also moisture. Packets that are stapled or taped do not provide the greatest protection; however, there are alternative protectors available that guard also against moisture. Protect your collectible coins when they are in storage by choosing a dry space and never one that is damp and cool, such as the basement.
