This is most likely a copper-alloy cent, not a copper-plated zinc cent. Lamination errors are very common on solid alloy cents. They are quite...
I'm not sure in this case if it's a doubled die or mechanical doubling. Although there isn't classic shelving, the height differential is...
Nickels are not "silver plated". They are a solid alloy of 75% copper and 25% nickel. Your coin could have an added layer of copper that is...
The coin was damaged outside the mint.
Sounds like you have an off-center strike with a mirror brockage on the reverse. This error occurs when a coin remains in the striking chamber...
Misalignments as great as 40% exist among U.S. coins. They are exceptionally rare, however.

The bust seems devoid of fine details. But the bust does not have the expected appearance of a filled die. I'm wondering if the coin is simply...
If errors are your primary focus, you might enjoy visiting the group that I host and where I spend most of my time....
I have little doubt that this is a filled die error. They commonly affect the date (principally the "4") on steel cents. I've always found this...
No doubt about it. Clashed dies.
The explanation would have to be die deterioration, then. It can sometimes assume a very strange appearance. Maybe there was something abnormal...
It could be a strike-through error.
I can't see any change in topograpy. It just looks like a discolored quarter to me.
Your drawing does indicate that there is modest finning of the rim. This is rather common on proofs as they're struck under higher pressure than...
5.08 grams is within normal tolerances. Since you report no finning, perhaps the die's rim gutters were a tad deeper than normal.
It looks to be an RPM. I have no idea which one of the twenty-two listed D/D RPM's it might be. It's certainly not a D/P variety, since cents...
It looks like die damage of some sort. I can't tell what kind of die damage it is from here.
Your enlarged image is not coming through. The small size of your first image prevents me from determining exactly what you've got. Unless the...
