An alternative explanation, and one that I have no way to disprove, would argue that, during the second strike, the coin was off-center toward...
I suspect that these are simply traces of first-strike letters that got smeared by the second strike but weren't completely erased.
The coin itself rotated slightly in a clockwise direction after the first strike so that the details of the second strike are rotated...
I can now confirm that the second strike features a horizontal misalignment of the anvil die (and collar). The greatest lateral excursion of the...
There are bonded pile-ups known that incorporate 30 planchets or more. You don't need a "soft" alloy, either. Dimes and nickels are sometimes...
The biggest possible misalignment I've seen amounted to over 90%. However, the impression on the planchet may have been made by a die fragment,...
Which coin are you now talking about, Matt or yours? In any case, U.S. coins with horizontal misalignments of 50% and greater are known....
Your Canadian cent is an ordinary double strike, with the second strike off-center. In a misaligned second strike, only one face is offset.
Matt is sending me the coin. There might be evidence of a third strike on the reverse, but it's hard to tell from the photos. It does look as if...
This is a double-struck cent. The first strike was die-struck on both sides, the second uniface. This could have started out as an elliptical...
The coin is a a genuine mint product. It probably had an assist, but there's no way to know for sure. The strength of the host token's design is...
These "rippled" coins are common. How they're created is unclear. But it's done outside the Mint.
Exactly what was done to the coin I couldn't say. But its appearance is wholly incompatible with anything that could be generated inside a...
It's most likely a linear plating blister. However, since the ridge weakens where it crosses some of the higher portions of Lincoln's coat, it...
This is an uncentered broadstrike.
As several others have stated, this coin shows a fake second strike. The obverse face was struck by a crude counterfeit die while the reverse...
You most likely have a cent struck on a planchet punched out of rolled-thin stock. Such errors can produce cents as light as 1.4 grams. A weight...
This coin is suffering from severe chemical damage.
One form of improper alloy mix error involves an abnormally high fraction of tin and/or zinc. This creates a brassy look and the coins are...
I'm reviving this ancient thread because I wish to retract the thumbs-up I gave the dropped letter on the Polk dollar. I have to drop it back...
