The coin dating from 270 AD depicts on its obverse side the Roman Emperor Valerian, the first Emperor to be captured as a prisoner of war. On the reverse side is a unique scene of the goddess Dido sacrificing at the Temple of Hercules before setting off to found Carthage from Tyre, the city in which the coin was minted. Like all individually minted coins, this piece is very unique and may be a re-strike of a previously issued coin.
