Tetradrachm - Eorynomos

Chios operated as a prosperous Aegean trading hub throughout the fourth century BC, and its silver coinage circulated widely across the eastern Mediterranean commercial networks. The island maintained enough political autonomy during this period — navigating carefully between Athenian pressure and Persian influence following the King's Peace of 387 BC — to sustain an independent mint with consistent output. The magistrate name Eorynomos appearing on this issue places it within a series catalogued by Mavrogordato as among the more legibly attributed of the mid-century emissions.

Chian tetradrachms of this phase are notably underweight relative to the Attic standard, reflecting the island's adherence to its own traditional weight system.
