Gary0920 New Member United States 21 Posts	Posted 07/14/2021 5:10 pm I scraped at it a little bit with the pointy end of a dental floss pick it didn't move or go anywhere Report this Post to the Staff
merclover Bedrock of the Community United States 10635 Posts	Posted 07/14/2021 5:31 pm That is a zinc rot blister forming around the mintmark (the most common spot for them to form). It will grow larger, then open exposing the zinc rot to the air which accelerates the process, literately eating itself. Spend it while you can! Report this Post to the Staff
ijn1944 Bedrock of the Community United States 19159 Posts	Posted 07/14/2021 5:34 pm Yes, given the photos posted, I'd agree with apparent zinc rot--perhaps triggered by split plating adjacent to the mint mark. Report this Post to the Staff

Yokozuna Pillar of the Community United States 4618 Posts	Posted 07/14/2021 6:56 pm to the CCF! with the others that it's a broken plating blister and not an error. It was a round raised area at one time, but it collapsed and left the outside edge raised. It's just zinc rot and has no value over face.

Dearborn Moderator United States 96214 Posts	Posted 07/14/2021 6:57 pm It looks like someone took a punch (nail punch) just outside the real 'D' maybe on a slight angle moving the surrounding metal to form the backwards 'C' we see now. Looking at the center of the punch mark - it look like exposed zinc core to me. I think I can seeslight tooling marks to the lower right of the anomaly That is my opinion.. Collecting since 1972.
