Wouldn't determining composition require invasive sample testing of the coin?
You certainly have a better eye for these things than me. I bet you hold the status of ringer in the cloud game.
The same holds for me for nano "S".
A nano "S" with only 1 known example?
I do understand. Perhaps I am not communicating very well. But if you issue a coin a forever grade and then subsequently down the road change the...

Doesn't that hinge on who the attributor is? Some simply recognize a new die marriage as a new stage in the progression of a variety. CONECA and...
My thought is filling a mint mark on a die wouldn't hold up very long to the rigors of striking coinage.
And a characteristic that is very difficult to emulate and mostly overlooked by nefarious numismatist.
Even if this is the case looking to the obverse could still provide you with some diagnostics. One aspect numismatics tends to ignore, which I am...
The progression of the obverse relative to the reverse remains linear irrespective of the number of obverse dies paired with a single reverse die....
I am not a VAM collector. All I am suggesting is perhaps the diagnostics you are seeking to confirm the reverse die progression of the O/S from...
Perhaps you'll find your answer looking at the other side of the coin.
