Tetradrachm

Ainos sat at the mouth of the Hebros River on the Thracian coast, a position that made it commercially valuable enough to sustain a high-quality silver coinage through most of the fifth and fourth centuries. The city came under increasing Macedonian pressure during precisely this period — Philip II was systematically absorbing Thracian coastal cities through the 350s, and Ainos lost its autonomy not long after this issue was struck.

The tetradrachms of Ainos are notable for their consistent weight standard and careful die work, attributes that reflect a mint punching above the political weight of a city perpetually caught between larger powers.
