Errers and Varietys Bedrock of the Community United States 74881 Posts	Posted 06/23/2019 5:05 pm That's called zinc rot. Not an error coin, just damage. PSD. It happens when the zinc core gets exposed to the air. The air slowly starts to eat away at the zinc. Goes to show how cheaply made the new Zincolns are. Errers and Varietys.

coop Bedrock of the Community United States 62064 Posts	Posted 06/23/2019 7:22 pm The cause? Split plating. The strike broke through the plating and exposes the zinc planchet to get oxygen. That starts a bad reaction that is the beginning of the end of the coin: Not a good thing. Very spendable. In time the zinc will all go away and it copper plating shell will remain.
