It sounds like a non-sequitur, but I think the term pretty much applies to a coin like this. I was fortunate to be the successful bidder on GC last night.
Super coin. That's the B-1 die marriage, I think. Rarity 2. I can't see any clashes on obverse or reverse so it might be Die State 1. Or, since the reverse is completely missing a normally weak star, the reverse might be Die State 4 after the dies were lapped.
