Diobol

Ainos, a Thracian coastal city at the mouth of the Hebros river, maintained its own coinage tradition well into the classical period despite sitting uncomfortably between Macedonian and Odrysian Thracian power. This diobol falls within the transitional phase following Athens' reduced grip on northern Aegean tribute networks after the Peace of Nikias in 421 BC — a moment that gave smaller minting authorities brief room to assert commercial independence. May's corpus distinguishes two die pairings within this narrow emission window.
