This is the third time I got a coin that looks exactly like this in my change. It could be damage or a missing clad layer error.
This is not a true Missing Clad Layer error because the front would be stamped. So it could be a lamination error. Lamination errors happen when part of the metal peels off. So is it possible that whole front peeled off?
Still I think it is damaged but not being an expert on errors I cannot say for sure. If you have any information just leave a comment below.
