Neat. Looks like a 2000-D. Maybe it is a major die dent? John1

I believe that it is an indent strike, caused when two planchets are struck while overlapping each other. The other coin would be 95% OC on the obverse and uniface on the reverse.

Looks to be an indent strike - struck through another planchet that was overlapping it slightly.

Thanks! I thought of the indent strike, but wouldn't that have flattened the rim? The rim is almost totally intact (tried to show that with the pics).

I'm not 100% sure why, but the rim is always like that on indent strikes I've seen, to varying degrees. I think it's a combination of the fact that the rim is upset (and therefore work-hardened) before it's struck, and because of the pressure provided by the collar. Also, devices are partially formed even through a strike-through (depending on the thickness), and since the rim is the highest relief part of the coin, it's formed even though it's getting struck through something as thick as a planchet.

I hadn't thought about the collar protecting it; that makes sense. Thanks Captain!

A reverse image might help?

Just took a real quick pic of the reverse; it couldn't be more normal.

It looks like the collar would protect the rim.
