Trihemiobol

Poseidonia — the Greek colony on the Tyrrhenian coast of Lucania — occupied an uneasy position between Etruscan commercial pressure to the north and indigenous Lucanian populations pressing inland. The city's coinage reflects a remarkably stable civic identity across this period, even as neighboring poleis were absorbed or disrupted. The trihemiobol, fractional by nature, was the working currency of daily market exchange, not treasury reserve.

The incuse technique used on early Poseidonian silver ties this mint to the broader South Italian tradition associated with Pythagorean-influenced cities — though the precise ideological connection remains debated among specialists.
