Diobol

Metapontion's small silver fractions circulated within one of the most agriculturally productive colonies in Magna Graecia, a city whose prosperity was so closely tied to grain that the barley ear became its defining civic emblem across nearly every denomination for centuries. By the time this diobol was struck, the city was navigating the turbulent aftermath of Pyrrhus of Epirus's campaigns through southern Italy, a period that strained alliances and disrupted trade networks throughout the region.

The diobol's tiny module made it essential for small daily transactions that larger silver fractions could not serve.
