Looks a little odd, doesn't it?: Lost something around the middle?: Must be a growing spurt?: So, it it PMD or something else? But wait, what about this weight?: And now this little bit of additional detail: So what caused this anomaly--a discussion for a future posting. P.S. this coin will be one of several I will award to the winner of a future GTG contest.
PMD. Likely a 'dryer coin'. Got stuck in a clothes dryer and was 'beaten' into having a wider/deeper 'rim'.
