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...
A lot of 1964 quarters purported to be struck on dime stock are not. This applies to both slabbed and raw coins. A true silver dime stock...
Fake. It's impossible to get proportional expansion of the design on both faces. I've seen a lot of similar cents. The plating is almost always...
This is one of the better-known cud/retained cud quarters. It's listed in The Cud Book. The obverse features a die break (cud). The reverse...
You'll find many fake unplated cents in slabs, even from some of the top-tier companies.
One good way to verify the authenticity of an unplated cent is to compare it to the unplated surface of a partially plated cent. The latter are...
The only unplated cents you can be sure about are those that retain original mint luster. This is one of the most commonly faked errors out...
Separate names with a comma.
