Quote: "numisquare"Based on the headdress this is probably from Varhran IV 388-399 AD. The name of the king would be in the green area on the right side of the coin. The year and mint should be on the reverse side, but are not legible.

This type of coin is not present in the numist catalog, it can be added.
