Wow! That is a coin in honor of the face on Mars. Worth billions. Just kidding of course. Maybe posting under the Ancient forum would help.
Loks like an ancient Greek coin from Parion in Mysia, c. 5th-4th century BC. Be careful. The face on the obverse represents a Gorgon. You may turn to stone if you look directly at it! https://cngcoins.com/Coin.aspx?CoinID=389567 https://cngcoins.com/Coin.aspx?CoinID=384311
