Bill Kerr Valued Member United States 425 Posts	Posted 01/16/2022 3:53 pm I have come across coins that look as though the minting process is not completed. Here is a coin that has a dull finish on both side, however, I also have one that is dull on one side and normal on the other side. Can you explain what has happened? Report this Post to the Staff

You cannot compare what happens on one coin with another as each coin may have had different elemental exposure. "Exposure" could be a chemical wash or just subject to a different airborne environment and/or handled differently. Report this Post to the Staff
