Just Bob Posted January 11, 2020 Share Posted January 11, 2020 Welcome to the forum. You did not post a question, so I am assuming that you want to know why your coin is pitted. In 1982, the US Mint switched the composition of Lincoln cents from a copper alloy to copper plated zinc. Zinc corrodes easily, and your coin has spots where the zinc was exposed to the environment - possibly by nicks or scratches - and developed what is known as "zinc rot." In other words, it is just damage. Link to comment Share on other sites More sharing options...
