Fabulous pattern, undisturbed except for the toning.
It seems that this coin has been in a coin cabinet for many decades, and the resins or glues in the wood have toned the surface to what we now see.
At least, I don't see any cabinet friction, as many highly valuable coins in the British Museum appear to suffer from.
That is why so many modern collector silver coins are encapsulated or are in slabs.
Would it have a higher value, had it been blast white?

I agree with GrapeCollects: - The reverse looks too European 'minor coin' in style, at a time when the United States was making a strenuous effort politically, to be different from Europe.
