1 Uncia dot to the left

Ariminum (modern Rimini) was one of the earliest Latin colonies established on the Adriatic coast, founded in 268 BC — the same year this coinage series almost certainly begins. The colony received its own bronze coinage as part of Rome's broader strategy of embedding monetary infrastructure into newly founded settlements along the via Flaminia corridor, giving colonists a functional medium of exchange without depending entirely on Roman supply lines.

The dot placement to the left is the diagnostic feature separating this die variety from otherwise identical Ariminese uncia production, as catalogued by Campana.
