Hi everyone,
I just got this nice Alexander III drachm from a reputable dealer.
It is 16mm and 4.11g, and I do not see any signs of casting. It looks good in hand.
However, I am not sure of where it was minted. I think that it is a posthumous issue, and there are mint marks to the left of Zeus and under his throne. I am unable to identify the symbol under the throne, but the symbol to the field left of Zeus looks like the mintmark of Miletos (Ionia). Or could this be a Celtic issue?
Any help IDing the mint of this coin would be appreciated!
