I wouldn't necessarily be harder on ICG than the other services. I've detected squeeze jobs in NGC and ANACS slabs. It doesn't happen very...
I wasn't able to borrow the coin from the seller, but he got a credit from NGC. It was an "enhanced error". Someone took a genuine broadstrike...
If the weight is normal, the coin perfectly round, and the reeding unaffected, then it could be an unusual struck-through error affecting both dies.
The coin that opened this thread is a squeeze job. A few months ago I also spotted one in an NGC slab. A slab is no guarantee of authenticity.
I guess Ken is using "plate shift doubling" in place of "plating disturbance doubling". "Split plating doubling" is okay.
There's no such thing as "plating shift doubling". Perhaps you're thinking of plating disturbance doubling. In this case, however, we're dealing...
It happens all the time. I've had a few columns dealing with clashed cap strikes over the past few months in Coin World.
This is a clashed cap strike, a type of brockage. A late-stage die cap clashed directly with the reverse die, picking up a fresh image on its...
It's the first double denomination error I've seen involving a Georgia quarter struck over a struck nickel. A great rarity that's undoubtedly...
I have trouble visualizing your scenario, Jim. If the coin had been struck through a clad layer derived from a half dollar with a curved clip,...
I am now confident that this is a genuine error of the type I've already descibed. Congratulations on your find.
I've seen uncounted numbers of clad coins (including half dollars) struck through detached clad layers. The result is a mushy design that tends...
If the reverse face is normal, then the obverse may have been struck through a detached clad layer. I'm hedging my bets on the identity of the...
It's definitely machine doubling.
Exactly how it was damaged is hard to say. But its appearance is completely incompatible with what can transpire within a coinage press.
This coin is badly damaged and nothing else. It was not struck by broken or damaged dies.
Someone popped out the core, flipped it over, and re-inserted it. It's not an error.
This coin was mechanically altered outside the Mint.
There is no question that this is a case of post-strike damage.
This is not an off-center strike. It's a minor horizontal misalignment of the obverse (hammer) die. It's not offset enough to be considered an...
