Onkia

Akragas in the late fifth century was one of the wealthiest cities in the Greek world — Pindar called its citizens the finest livers among mortals — and yet bronze coinage was a late and grudging addition to its monetary repertoire, introduced only as small-denomination silver became impractical for daily market transactions. This onkia, the smallest unit in the Sicilian bronze system, represents a fraction of the litra and circulated in a city whose silver output had been among the most prolific in the western Greek world.

The Carthaginian sack of 406 BC ended Akragantine minting abruptly, making this entire bronze series a compressed episode of roughly two decades.
