I "think" I have seen similar coins to this but they never seem to have much value. Not my pics and this is part of a US coin purchase lot. I am curious if someone could help with identifying. I am assuming it doesn't have much value? Maybe $50?
It looks like counterfeit/replica Sicilian tetradrachm. Greek coins aren't my main specialty so I'm sure others can give more input.
An original of what this coin represents is not cheap. For example, this coin (NOT MINE) is for sale on Vcoins for $1800
