Tetrobol - Philaios

Abdera's coinage from this period reflects the city's remarkable prosperity as a major trading hub on the Thracian coast, despite the disruptions of the Peloponnesian War playing out across the Aegean. The magistrate name Philaios appears on a defined group within May's classification, identifying the issuing official responsible for this emission — a Thasian colonial practice of civic accountability that Abdera retained long after its refounding.

May 427 falls within a sequence showing careful die management, with relatively few obverse dies serving the tetrobol denomination across the Philaios issues.
