Well….. This site has some of the most educated collection of ancient coin folks around. Thing is, they tend to stay in the ancients forum. Go back to the main page and look for the tab that says “Ancient Coins” and post your coin there. You will be covered up with information in no time.
As a dealer I would offer $50, looking to sell around $75. That's IF I determined the coin to be authentic. There was a hoard of these that entered the market back in the 80's that were eventually determined to be forgeries, and you still find them floating around, even in respectable dealers' inventories. Does the coin have any provenance?
