Istros, also known as Histria, was an ancient Greek colony located on the western Dobrudja coast of the Black Sea. Situated approximately 300 miles north of Byzantium, this small city was founded by Miletian traders around 657 or 656 BCE. As the oldest Greek colony on the Black Sea, Istros survived for some 14 centuries before its eventual abandonment in the mid-seventh century CE.
These coins portray essentially identical dual portraits of the sun god Apollo on their obverse. Historians believe that the eagle represents Zeus and the dolphin the Black Sea. "The Mystery of the Double-Headed Coins of Ancient Istros" [Coinweek.com]
