@Mary Neely I want you to think very carefully about how you answer my question. If this was a Mint error, what do you think could have caused it? Chris
Just circulation wear and tear. Could occur just on one side. Could of been propped under a table leg to keep it from wobbling.
This tells me that you need to learn about the minting process before you start looking for errors. Otherwise, every coin with even the slightest damage will look like a possible error to you. And, there are probably millions of damaged coins floating around in circulation. Chris
I have seen similar to these on aliexpress as a "hobo" penny. Copper is easier to carve than nickel compounds. Maybe an imitator.
