This is a “silvered billon” (mixed metals) coin (-2.4 g) featuring Empress Salonina, who ruled during the Roman Imperial period around 254-268 AD with her husband Roman Emperor Gallienus. An image of her bust adorns the obverse. The design on the reverse closely matches a variety that was minted around 260-268 AD representing Salonina (instead of a goddess) seated and holding an olive branch and scepter.
