This coin is a Greek silver tetradrachm minted in The Islands off Thrace in circa 140-110 B.C. The obverse shows Hercules and the reverse shows Dionysus.
Hercules (known in Greek as Heracles or Herakles) is one of the best-known heroes in Greek and Roman mythology. His life was not easy–he endured many trials and completed many daunting tasks–but the reward for his suffering was a promise that he would live forever among the gods at Mount Olympus.
Dionysus was the ancient Greek god of wine, winemaking, grape cultivation, fertility, ritual madness, theater, and religious ecstasy.
