Avoid touching your coins as much 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 must handle your collectable coins you should try to hold them only on the edges, especially with mint condition coins.

You should try to avoid cleaning your coins and if it has to be done, the process should be handled by a specialist. Rather than cleaning a coin, leaving its patina undisturbed might make it more desirable to collectors and more valuable.

Moisture can cause problems just like fingerprints and dust can, so even though most holders are sufficient to protect your barber quarters make sure your most valuable pieces are really protected. Aside from the typical stapled or taped packets that provide average protection, there are other protectors out there that can do a better job and guard against moisture as well. 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.
