These lines could parallel scrape marks from a feeder finger. They certainly represent a kind of die damage. As far as die clash being a thing...
The raised area represents a small area of die damage. Perhaps a die gouge or a short die dent. The missing copper is where the copper plating...
It was damaged/altered outside the Mint.
The photos are poor, but if both the date and the mintmark are doubled, then it's most like strike doubling (machine doubling). This is very...
The cent has been damaged outside the mint. The quarter does indeed show finning of the rim, undoubtedly due to excessive striking pressure.
The proper term is "die chip". These are quite common.
It's not a repunched mintmark. The copper plating simply split around the "D" when the coin was struck. This is rather common.
Interesting. But how do you KNOW it is mechanical doubling, as opposed to a doubled die? Is there flat, marginal shelving elsewhere in the...
Those doubled designer's initials do look like a doubled die. If it was strike doubling, these small, isolated elements would exhibit classic...
It's an example of die deterioration doubling (DDD). The orange peel texture of the coin's surface supports this conclusion.
Strike doubling is often uneven. Exactly why is sometimes unclear. As I said, I'm not sure it's strike doubling. Since proofs are struck more...
It looks like it's probably strike doubling (machine doubling). Interior features won't show the flat shelving that occurs at the margins of the...
A Lincoln cent struck by the same die sold for over $20 on eBay recently.
I would assume it's a filled die error. Some crud lodged in the recesses of the die face corresponding to the missing stars.
Probably just an effect of die deterioration. I think I see a low ridge extending up from the point of Lincoln's bust. That would also point to...
Nope. But choosing a Yahoo I.D and password is a simple task.
By the way, Speedy, if you're going to get serious about errors, you might want to spend some time on the on-line group that I host....
You mean a quarter struck on a nickel planchet? That's an entirely different error from a wrong stock error, and yes, it will be smaller than a...
Right, there's no way to check without cracking it out. And once you do, it's Catch-22. You've got to check the weight. A quarter on nickel...
Grading services only guarantee authenticity. And once you break a coin out and find out it's fake, you're out of luck. Grading services do not...
Separate names with a comma.
