I'm familiar with these 1926-D quarters with collar cud and die breaks, but what's that Miss Liberty seems to have tucked into her chain mail? It doesn't match up as a clash with the reverse die, and is definitely an integral part of the coin, as-struck. So, what do you think this is?
So we need to find out what others countries the Denver mint was minting for? Thinking the obv. Die clashed with a die of a foreign nation. Any clues?
Good thought Paddy. We probably shouldn't overlook the minting of commemoratives of that period either.
There is a gentleman in CONECA that all he specializes in is error/variety Standing Liberty Quarters. You might want to reach out to CONECA and get his info and see what he has to say. Maybe a new variety! Nice.
From the edge design... found it. It's an off-center die clash. Like the Snow 1 variety of the 1880 Indian Cent. Now, I want some sort of discovery credit.
I've looked at all US Classic commems between 1925 & 1928, (both silver and gold), and find no match there either. Foreign coins are my last best hope . . . Unfortunately, I know nothing about them.
That pattern at the rim has the right look, but I'm unconvinced. That pattern exists only on the obverse side, and I can't see how it would produce the raised negative on the same side of the coin. I'll gladly consider any supportive theory you put forth.
Hmm. But the negative "tear drops" seem the right size and to be moving on a curve, like the edge design. Perhaps a lamination flake deposited itself on that area of the die.
Not so convinced that it is a clash. A clash typically occurs on the raised fields of the die. This would be part on the incused design thus not be susceptible to die on die damage. Could it be due grease gunk debris that fell on to the die during striking or that broke away during striking. Similar to the WV state quarters on the reverse?
I assume you are referring to a strike through dropped letter. That would leave an impression into the surface of the coin, rather than a raised feature.
