This 2013 D has a delam scrap from an earlier version of the Lincolin cent. You can see the design from the 2013 through the delam. Also the delam is reversed. Can anyone help with how this could happen at the mint?
It can't happen at the mint. We see these quit often on the Forum. Someone puts some glue on a coin and presses another coin over it creating a reverse image. As stated, soak in acetone and it will return to it's original state.
