1967 Quarter "Error or PMD"

[cebell]

I need help with this because I've never seen anything like it. If I were to speculate... it looks as if it was struck on a Planchard that already had the damage.

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.

Is it possible that these holes could be from Rockwell testing in the 60s?

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.

I agree with Gary. Rockwell testing left a single, small divot. This one is definitely damage.
