nickelsearcher Moderator United States 15976 Posts	Posted 05/24/2026 11:59 am I don't see this as a lamination. I think it's some form of staining. Take a look at my other hobby ... http://www.jk-dk.art Report this Post to the Staff
JustRandomCoins Valued Member Australia 102 Posts	Posted 05/24/2026 7:55 pm Thank you for your inputs, appreciated it and guided to me a conclusion. I have acetone bathed it for a day so it's not a glue or anything similar. What was throwing me was the cracks complimenting the damage, however laminate errors are in straight lines and a clad layer error would make it weigh less. My conclusion is this coin suffers from post-mint environmental acid corrosion that has deeply eaten into the copper-nickel alloy, leaving behind green verdigris crust and corrosion, revealing the under-surface alloy, which has induced stress corrosion cracking (SCC). All of which is PMD. Report this Post to the Staff
