A related form of die wear occurs in copper-plated zinc cents, beginning in 1982. However, it tends to be more localized. In that case, it's...
This form of wear is common in recent dimes and America the Beautiful quarters. Here's a discussion from 2013:...
While die deterioration doubling is a possiblity, it's more likely a case of plating disturbance doubling.
Yes, the position of the collar break changes with respect to both faces.
This is definitely NOT a grease strike. It's an example of severe die wear (die deterioration).
A typical missing clad error involves a clad layer popping off after blanking and will weigh 4.67 grams (a clad layer weighs 1 gram). This coin...
It would be a "die error" according to the classification system I use. I don't know what caused the damage, but was something that "clawed" the...
Die damage.
Yes. But my speculation is based on the lack of any trace of a persistent proto-rim along the outer margin of the obverse face.
The lead-off coin is a partial collar error. It may also have been struck on a blank.
Actually, scratch that comment about the SBAs. It may have been the dies that were chemically etched. Too long ago to remember clearly.
They were loaned to me years ago by Fred Weinberg. I returned them long ago and took no photos.
I don't know what caused it. I have encountered a large series of BU SBA dollars that were chemically etched after the strike. I don't know what...
If my conclusion is correct, then it would have to be post-strike. If it was pre-strike, then the odd texture would have been erased in the...
The coarse texture of the affected area, the presence of a discernible "grain", and the fact that it continues onto the edge suggests chemical damage.
It's most likely a case of plating disturbance doubling. During the strike, tensile forces are concentrated at and near the edges of the design....
You have a rim cud that amounts to about 90 arc degrees. In other words, the rim gutter of the obverse die broke off here. Definitely worth keeping.
This is clearly a case of severe die deterioration, pure and simple.
I have seen many forms of peripheral die damage that parallel (and sometimes replace) the design rim. Most represent die attrition errors (where...
It's some form of peripheral die damage. Based on the photos, I would tentatively guess that this is an example of collar clash. A more...
