Brandmeister Pillar of the Community United States 6464 Posts	Posted 12/14/2024 5:10 pm Not quite sure what is going on with this quarter. The obverse seems to have a slight MAD that raised a Rim Fin. However, on the reverse, it seems like there might be a collar clash? The two features are in the same area, but not completely aligned. I was under the impression that the hammer die is what produces a single sided misaligned die strike. But I was also under the impression that only the hammer can suffer a collar clash, because the anvil die doesn't move relative to the collar. Am I misinterpreting one or both of the striking events on this coin? Report this Post to the Staff

Dearborn Moderator United States 94922 Posts	Posted 12/14/2024 8:52 pm Rim Fin on first image, collar clash on second image, all because of a mis aligned die. Collecting since 1972.

Brandmeister Pillar of the Community United States 6464 Posts	Posted 12/14/2024 9:12 pm Dearborn, hence my question. The MAD is on the opposite coin face from the collar clash. I thought those are both hammer die phenomenon, but obviously both die weren't the hammer. Report this Post to the Staff

Brandmeister Pillar of the Community United States 6464 Posts	Posted 12/15/2024 10:41 am Makecents, I think maybe you nailed it. The marks resemble a milder version of the Virginia quarter shown in the article. The misalignments on this coin are just about 90 degrees from each other. You'd expect 180 for tilted, or 0 for off center strike. The article describes a chaotic production run, and I rather imagine producing the huge number of bicentennial quarters was nothing short of a fire drill at the Mint. I'd call that the leading theory unless we find a better one. Thanks! =) Not sure why that article didn't come up on Error Ref when I searched for "collar clash". Report this Post to the Staff
