Conder101 nailed it. Is it for sale? In any event, I'd like to write it up for Coin World.
I'm completely stumped. I can't see how they could be clash marks. Their symmetrical appearance seems to fly in the face of any kind of random...
As others have said, this coin was damaged/altered outside the Mint.
No. The thin, abnormally weak lettering is due to recession of the field portion of the die. This is "design-devouring die wear".
It wasn't struck through anything. The weakness is entirely due to die deterioration.
Good point.
It's impossible to say whether this had help. I have seen several in-collar triple strikes, so it's not hard to conceive of an in-collar...
Most off-metal and wrong planchet errors are struck on blanks. That's because the undersized blank betrays no sign of passage through the upset...
I'll try to remember. They don't appear very often. Some of these errors, like the one I've shown, have an incomplete pattern of copper...
This coin also shows an abnormal pattern of upset. For what it's worth, this coin was extracted from a PCGS slab.
Here is one of several cents I own with a bulls-eye pattern of copper deposition (or zinc exposure): [ATTACH] [ATTACH]
If the blemish is truly raised, then it could be an accidental die scratch. There is no way to establish what might have caused it. Your photos...
Sorry, but I don't see anything that could be construed as an error. And the reverse features Monticello, not any sort of "memorial".
NGC blew it, in my opinion. It wouldn't be the first time. None of the grading services are particularly reliable when dealing with...
The second strike was from a fantasy/counterfeit die. Many such double strikes pop on eBay with regularity.
The collar was not broken. The collar was fully intact. It simply wasn't fully deployed and it was pushed further down as the expanding coin...
The stepped line and the upward-sloping perimeter are part of the same error -- a broad die dent. The step marks the edge of the die dent. I...
It's certainly not post-mint damage. The grading services have a habit of over-counting (and sometimes undercounting) the number of strikes a...
I see no persuasive evidence that the coin was struck more than once. The sloping edge with smeared reeding is simply evidence that the coin...
It's a late-stage brockage.
