Hemidrachm

Orchomenos was the dominant power in Boeotia before Thebes eclipsed it, and this hemidrachm falls squarely within the period of that rivalry. The city's autonomous coinage effectively ended after 364 BC, when Thebes razed Orchomenos following the discovery — possibly fabricated — of a conspiracy against Theban hegemony. The massacre and enslavement of its population stands among the most brutal acts of the post-Leuctra settlement.

The BCD Boiotia reference places this among the most thoroughly catalogued series in Greek numismatics, courtesy of the collection assembled over decades by the collector known only by those initials.
