Haha I'm looking at the East side of the obverse, and reverse. I see a big groove inside the rim. On the reverse it almost cuts into the top of AMERICA. However the letters are :"on top" of the groove and are not damaged.
The outer tips of the letters in AMERICA extend out past the edge of the crevice. They are normal height. I think it would have to be a planchet error, or the planchet was damaged during the strike. The die would have to come together after the groove was impressed for the letters to be raised above the level of the groove. What I'm saying is it cant be post strike damage or the letters would be pushed down into the groove.
