Æ20

Istros, a Milesian colony on the western Black Sea coast near the Danube delta, was one of the earliest Greek settlements in the region and maintained an active mint through much of the Hellenistic period. The city's coinage circulated primarily within the local Pontic trade network rather than reaching broader Mediterranean commerce, which accounts for the relatively high frequency of well-preserved examples — limited circulation range meant limited wear.

SNG Copenhagen 41 and Rogers 187 place this type squarely within the established series, though the two-century attribution window reflects genuine scholarly uncertainty about Istrian bronze chronology rather than careless dating.
