Dichalkon

Ainos, a Thracian coastal city at the mouth of the Hebros River, maintained enough commercial independence through the Hellenistic period to issue its own bronze small change despite repeated pressure from Macedonian and later Lysimachean overlords. The dichalkon denomination served local market transactions that silver simply couldn't reach efficiently — fractional bronze like this was the currency of the agora stall, not the treasury.

AMNG II#381 places this within Imhoof-Blumer and Pick's foundational corpus of ancient Greek bronze, a classification still used by specialists where later scholarship hasn't superseded it.
