This coin is extremely rare with Athena Ergane on the reverse not wearing a helmet and with two olive leaves in the lower right corner, which is typical of the early issues of the Civic Mint. We had an example of this in the Gemini Rockefeller sale which was only VF, but did not have the cheek porosity that this coin has on the obverse. It brought a hammer price of $35,000. Less than ten coins of this rare issue exist. Perfectly centered with some contact marks. VF
