Dearborn Moderator United States 99376 Posts	Posted 09/24/2023 2:11 pm a pretty intense Ridge Ring. Collecting since 1972. Learning from then on "Tell me and I forget. Teach me and I remember.

Cujohn Pillar of the Community United States 7174 Posts	Posted 09/25/2023 6:02 pm As far as the fingerprint being imbedded on the reverse, that's what the oils and chemicals from a fingerprint will do to coins. They destroy the surface. Edited by Cujohn 09/25/2023 6:02 pm Report this Post to the Staff
