No, I don't think you're going to find these on your error websites. That is to say, unless they speculate in the macabre. This is what's perhaps even the more fascinating, they're different coins, but from the same date and mint; both 1998-Ds. Theorize away...
It looks like a strike through rim burr, all of which was from the core, and none from the clad layers.
They are actually struck-in rim burrs. That is to say, these were struck in these planchets. That is to say, this is how these planchets looked before they were struck by the dies. That is to say, you did get the "strike" part right, lol...
I thought rim burrs are shaven metal copper bits. That's what it says in the error reference lol.... meh lol I don't get how I'm wrong lol. Plastic part I was wrong.
Ever take a Rorschach test? I see the shark, too, it has its mouth wide open. I wonder what that means, whether we should be worried?
Yeah, it is kind of funky. It is just not something that was sandwiched between the die and planchet, as we'd think in the case of a strike-through, but was struck-in or embedded in the planchet before the die struck the planchet.
Idk I might be stupid or just see things different, but i see a sperm whale. The one king through half looks like the whale. And the one going through trust looks like a whale fin lol
I may have something to learn here . . . My understanding is that a rim burr extends from the edge of the planchet as the result of being imperfectly sheared by dull punching dies, and then is folded over and struck into the coin in the striking chamber.
Here, I just found this from Mike Diamond: "This is a struck-in rim burr, a form of pre-strike planchet damage." http://board.conecaonline.org/showthread.php?3432-RIM-BURR PS: So it appears you have the chain of causation right. It's on the planchet but not embedded in it, as I had thought, but rather flattened into the coin as the die came down on it. Does that make more sense?
Yeah, I get that Eddie . . . what I'm questioning is the notion that the burr is embedded into the planchet before it reaches the coining press.
