Hemiobol

Aspendos, the prosperous Pamphylian city controlling the Eurymedon river trade route, began striking its own silver coinage in the late fifth century as commerce with the Greek world and Achaemenid-administered interior demanded a reliable local currency. The hemiobol sat at the fractional base of that system — small enough that individual specimens were routinely lost in antiquity, which partly explains why survivorship is thin despite what must have been substantial original production.
