Hmm. I have no idea on this one! Pretty interesting. Edit: I'm leaning towards PMD (post-mint damage), but I will defer to those with more experience in error coins.
PS- looking at the weird sort of hexagonal-ish shape of the unsquashed areas and the apparent hits to the obverse makes me think this looks more like tool damage of some kind rather than something that would've happened in a coin press at the Mint. So I lean even more heavily towards PMD at my second look, but I'll still defer to others with more experience.
PMD and I put up arrows to what's left of the reeded rim, after it was peeled of off the copper center, or zinc .
Okay, please bear with me! My Dad used to have a huge vise that was shaped like a blacksmith's anvil, and the round bar that turned the screw drive to open and close it was about 1" in diameter and 14" long. The whole thing weighed more than 50 lbs. and my Dad custom-built a large work table in the garage on which to bolt it in place. He used this vise to hold axes in place while he sharpened them. My Dad was a firm believer in overkill. Believe me! If he wanted to hang a picture on the wall, he would probably use an 8-penny nail. Anyway, it looks like this coin may have been damaged in a two-step process. First, some sort of straight-edged, steel tool was hammered into the obverse face of the coin, and then the outer edges were (literally) crushed in the jaws of a large vise. So, that's my story, and I'm sticking to it! (Mary Ann from Laugh-In ) Chris
