Æ21

Ainos, a Thracian coastal city at the mouth of the Hebros River, maintained a remarkably independent civic coinage well into the period of Roman consolidation in the region. The city had passed through Macedonian, Ptolemaic, and Seleucid spheres of influence before settling into a kind of nominal autonomy under Roman oversight — a political ambiguity that this long bronze series reflects in its absence of any royal or imperial authority's name.

The date range spans the city's last century and a half of meaningful civic independence before Roman provincial reorganization effectively ended local monetary production.
