ijn1944 Bedrock of the Community United States 19155 Posts	Posted 03/01/2024 07:44 am I suspect that's caused by split plating associated with the mint mark. Coin is struck, plating is split, and the zinc core becomes exposed, which eventually leads to zinc rot. Not uncommon in 1980s-1990s zinc core cents. In this case, it appears some circulation wear has further 'shaped' the mint mark. Report this Post to the Staff
