Poor Lincoln has gone through a tough life in this circulation. LOL Thanks in advance! Report this Post to the Staff

ijn1944 Bedrock of the Community United States 19277 Posts	Posted 02/26/2023 4:29 pm Given that the coin is a zinc core Memorial cent, I'm thinking we have a plating issue--perhaps very early stage split plating, which will lead to zinc rot--not uncommon with 1980s zinc cents.

Curly82ABN Valued Member United States 177 Posts	Posted 02/26/2023 4:40 pm Thanks, ijn1944! I hear what you are saying, and agree. The odd part is that the circle around the MM is fairly a perfect circle. Report this Post to the Staff

Curly82ABN Valued Member United States 177 Posts	Posted 02/26/2023 5:30 pm Really appreciate all the feedback! I just came across some information that explains this to the tee "A corrosion dome formed around the Mint mark of this 1983-D Lincoln Cent and later burst through and emptied out. Information provided by Mike Diamond" Here is the link to CoinWorld (It is the 7th one presented, so click right), https://www.coinworld.com/news/us-c...es-vary.html Was fortunate that the example is a 1983D LMC.
