Tetradrachm In the name of Alexander III, Erythrai

Erythrai, on the Ionian coast of Asia Minor, was among the Greek cities that continued striking Alexander-type tetradrachms well into the second century BC — decades after Alexander's death in 323. These issues were not nostalgic tributes but practical monetary decisions: the Alexander type had become a de facto international trade currency across the eastern Mediterranean and beyond, and cities with active commercial ports had strong incentive to keep producing a coinage their trading partners would accept without question.

The Kinns reference places this issue within a documented sequence tied to the city's magistrate system, allowing approximate dating despite the absence of regnal years.
