Hemidrachm

Sinope was the dominant Greek colonial city on the Black Sea's southern coast, controlling trade routes between the Pontic interior and the Aegean world. Its coinage circulated widely among merchants handling grain, timber, and slaves — the economic backbone of the region. The city retained minting autonomy even as Pontic royal power expanded around it, which is why civic issues like this hemidrachm continued alongside and sometimes in spite of royal propaganda coinage.

HGC 7 places this type within a well-documented civic series tied to Sinope's magistrate system, individual officials' names or monograms appearing on the dies as accountability markers.
