 It would have been impossible to get this from a planchet that had been damaged before striking. The strike would have obliterated most (if not all) of that damage. This is post mint damage. It appears that someone struck the coin with a sharp object.Bob Piazza

 No, most of the Rockwell tests were done on the side of the dies and not the area where the die impression is. This coin is clearly abuse done outside of the mint. The Rockwell tests were typically done once and that was it. This looks tike a hammer and punch job.Originally posted by cebell View PostIs it possible that these holes could be from Rockwell testing in the 60s?
