1983-D Not Sure What To Call It Yet But It Definitely Caught My Eye...

i cna not tell what you might be refering to...
telling us what you are seeing might get you some resopnses...

i am no expert - but I see a fairly ordinary coin...

I see a normal coin from a normal die. But what I do notice is that the die state is very fresh. That maybe what you see seeing as different. No die flow even near the rims. Often these stand out and you don't realize why? It is because of the die die state, that something looks different. The only weakness is on the 'STA' on STATES, which is also normal as the highest relief is on the opposite side of that area on the coin. I would save it as an EDS coin. (Too bad it isn't a BU coin) Does the obverse look this nice on the fields?
