Tetradrachm

Ainos, a Thracian coastal city at the mouth of the Hebros River, punched well above its political weight in the late fifth and early fourth centuries. The city's silver coinage was tied directly to its position as a key transit point for Thracian interior trade, and the tetradrachm series of this period represents the mint operating near peak output before Ainos fell under increasing Macedonian pressure. The specific window of 398–395 BC places this issue contemporary with renewed Spartan intervention in Anatolia under Thibron and then Derkylidas — regional destabilization that made Aegean coastal mints acutely conscious of their own autonomy.

May's die study remains the essential reference for sequencing this series, and #348 falls within a well-documented late grouping distinguished by subtle shifts in die axis and punch depth.
