The odd appearance of the obverse has more to do with inadequate upset and an excessively convex die. This appearance is the norm in 1985-D dimes...
I'd be happy to examine it for you at no charge. It would be very cool if this is another example of a sunken die error affecting the entire die...
This is not garden-variety die deterioration doubling. In the affected New Hampshire and New York quarters, it's only the peripheral letters that...
This is an unusual form of localized, premature die deterioration doubling. It is mainly seen on New Hampshire and New York quarters.
I'd say between $200 and $300 dollars. Maybe more if you can connect with someone who specializes in these issues.
I also haven't seen any bonded steel coins or ones made out of pure, elemental nickel. But I wouldn't be surprised if some turned up. Melting...
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...
