Cujohn Pillar of the Community United States 7174 Posts	Posted 11/21/2023 6:42 pm Quote: So was the collar broken, but the section was only pushed back and not lost completely? The piece of the collar was missing. The bulge is from how much pressure the planchet was stamped with. Report this Post to the Staff
Brandmeister Pillar of the Community United States 6814 Posts	Posted 11/21/2023 7:34 pm Right, I understand the strike pressure deformed the metal through the gap. But the excess edge seems rounded in the same circumference as the rim and collar, just offset a short distance. If that collar piece were totally missing, wouldn't the edge look broadstruck? Although I guess the gap isn't huge relative to the circumference. Report this Post to the Staff
tropicalbats Pillar of the Community United States 6182 Posts	Posted 11/21/2023 8:48 pm Thanks so much for all the great comments! It's just not an error that you see very often so was glad to get a chance to put one up. As to Brand's question, the collar piece is gone. It's just that the planchet that expanded at the break was already the correct diameter and had gone through the upset mill so all that really happened was that it pushed out radially through the gap. Yes, it is the same process as a broad strike, only here most of the collar is in place so the coin is still struck pretty much the same thickness and doesn't really moosh out in a funky-looking way. It just goes straight out. Report this Post to the Staff
Brandmeister Pillar of the Community United States 6814 Posts	Posted 11/21/2023 9:08 pm That makes sense to me. The planchet has a proto-rim, and the remaining collar prevents the dies from producing a broadstrike. Thanks for the explanation! =) Report this Post to the Staff
