It’s best to handle your collectible coins as little as possible. In the world of collectible coins, value is directly correlated to condition and quality, which is lessened when scratches, smudges, fingerprints or scratches 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.

You should try to avoid cleaning your coins and if it has to be done, the process should be handled by a specialist. Removing a coin's slowly developed patina might make it less tempting to collectors and possibly less valuable.

Most holders provide adequate protection for seated liberty dimes but you will want to be sure that your most valuable coins are protected not only from fingerprints and dust, but also moisture. Stapled or taped containers don’t protect very well, but there are other options available that can also block moisture. When selecting a storage space for your collectible coins, make sure they are not in an area given to dampness, such as a cellar or basement.
