How can you tell the difference between this type of mint error and PMD? The nuances escape me and I am very curious about it. Thanks! |

Quote:How can you tell the difference between this type of mint error and PMD? This type of error would be almost impossible to replicate unless you had access to a press and Memorial reverse die. Just about everyone reading this post has probably seen a coin struck through a capped die, it is fairly common as far as errors go and only has a modest premium unless a strong brockage is displayed. The error pictured here is the actual die cap in all its flattened glory, an error that is much rarer than the resultant struck-through errors. Die caps occur when a struck coin fails to release from the dies and adheres to one of them, this results in the coin(die cap) now acting as the die. The first couple strikes result in a perfect mirror brockage, another rare and highly desirable error. As the die cap continues to strike coins, the planchet spreads out and wraps around the shank of the die. This stretching process also typically breaches the plating, giving the exposed zinc a "sunburst" appearance. Notice that the reverse detail is essentially perfect so that means it was the reverse die that was capped which preserved the detail. As the obverse continues to act as a die, the obverse design detail is flattened and stretched out, expanding as the planchet expands. The last few strikes made by this cap were still brockages since the obverse detail is largely preserved but that type is not nearly as rare or sought-after as the mirror type. If this coin had continued to cap the die, the obverse detail would have eventually been a ghost image or completely obliterated, resulting in the more common generic(not identifiable by date/mm) struck-through capped die errors. |

 Biokemist6 I paid more than I would have liked to on this one. But not too over the top. Coin will either be sent to NGC or PCGS for slabbing and grading. Not sure, on a tight budget at the moment. |
