Obol

The Perrhaiboi were a Thessalian tribal federation whose coinage was struck sporadically rather than as part of a sustained civic mint program. This obol falls within a brief window of the early Classical period when the confederation exercised enough political coherence to issue independent silver — a situation that would repeatedly collapse as Thessalian dynasts and outside powers competed for dominance over the region's fractious tribal structures.

BCD Thessaly I #1235 places this piece within a tightly argued sequence. The BCD collection, assembled by a single dedicated specialist over decades, remains the definitive organizational framework for Thessalian regional coinage precisely because institutional scholarship had largely neglected it.
