This appears to be a retained interior die break. A piece of the die face broke off and sank into the surrounding softer metal. The result is a...
It's a form of die deterioration (die wear, die fatigue, die deformation) that's commonly found on copper-plated zinc cents. It does occasionally...
The top coin appears to show post-strike damage. The bottom coin seems to show blistered plating. Of course, it has to be copper-plated zinc...
Broadstruck dimes are worth about $5. A grading service will charge way more than the coin is worth. So there's no point in submitting it.
I agree with "foundinrolls", it's a "glue job".
It looks like mechanical doubling to me. And yes, the coin was reprocessed.
I presume you are proposing that a cent planchet was struck by nickel dies and then struck again by cent dies. This is just about impossible, at...
It looks raised. If so, it's either a die chip, a die gouge, or a sharply defined die dent.
First of all, a cent struck again by nickel dies is not a "mule". It is a "double denomination" error. Second, a genuine double denomination...
Die chips and die cracks.
I confess that I don't see any doubling. Only some distortion of the letters due to die deterioration.
One diagnostic is omitted. On most clips the design rim tapers and fades out as it approaches the clip. Other than that, it's a good summary of...
I would think a lamination error is much more likely. These are much more common than strike-throughs and 3 cent pieces composed of Cu-Ni are...
Annealing softens the die. So presumably the punching-in of letters is done after annealing.
It's not hub doubling (in other words, not a doubled die). One theory is that, in the preparation of a master die, each letter punch is tapped...
The small photos show an unnatural gleam to the coin. A gleam consistent with plating. Of course, it could be a genuine error that was dipped,...
I think it's called "reducing lathe doubling" or something similar. It is said to occur in the production of a master hub. If so, then it would...
It's either a lamination error or a strike-through error (struck through a lamination flake). Only close inspection could discriminate between...
Longacre doubling is not mechanical doubling. Opinion is divided as to its cause. It seems restricted to 19th century coins. I believe it is...
Since it has original mint luster, I would think it's a genuine "black beauty" nickel. As to what causes the black color, opinion is divided. I...
Separate names with a comma.
