1 Semuncia

Ariminum (modern Rimini) was among the earliest Latin colonies to strike its own bronze coinage, authorized following Rome's establishment of the colony in 268 BC — the same year Rome introduced the silver denarius. The colonial mint operated with considerable independence during this window, producing cast and struck bronzes before Rome gradually consolidated monetary authority across the peninsula. The semuncia represents the smallest fractional denomination in this colonial series, and surviving examples at this weight are uncommon; most have shed grams through corrosion or deliberate clipping.
