Dearborn Moderator United States 98548 Posts	Posted 06/12/2022 12:23 pm That looks like a zinc bubble that popped open. Soon the zinc will be exposed and at that point this coin is doomed to rot away. You can see the same effect on the rim and bowtie as well. Collecting since 1972.

Garbanzo Valued Member United States 114 Posts	Posted 06/12/2022 12:52 pm Yes the coin has some zinc rot. But this looks too uniform and symmetrical. I need more opinions. Report this Post to the Staff

ijn1944 Bedrock of the Community United States 19255 Posts	Posted 06/12/2022 1:13 pm Yes, zinc rot. I've seen hundreds of these (zinc rot mint marks on zinc core cents) over the decades of roll searching. Report this Post to the Staff
Yokozuna Pillar of the Community United States 4618 Posts	Posted 06/12/2022 1:36 pm to the CCF! lots of Zlincoln cents with damage like this. On a personal note, I have a single entry to my credit on Urban Dictionary for the term "Zinc Rot." ANA ID: 3203813 - CONECA ID: N-5637 Clean a coin that may be worth collecting? Please DON'T! When in doubt, leave it dirty!! Report this Post to the Staff

coop Bedrock of the Community United States 62064 Posts	Posted 06/12/2022 10:08 pm Split plating creates zinc rot as the oxygen breaks down the zinc when it is exposed. Report this Post to the Staff
