1 Uncia Sunburst series

Populonia, a coastal Etruscan city-state near modern Piombino, was among the very few ancient mints to produce bronze coinage denominated in the Roman uncial system while remaining politically independent of Rome. This piece belongs to the Sunburst series struck during the Second Punic War — a period when Roman-allied and semi-aligned Italian communities alike faced pressure to sustain military supply chains. Whether Populonia struck these coins to meet tribute obligations, pay mercenaries, or simply facilitate local trade under wartime disruption remains debated.

At one uncia — one-twelfth of an as — this is the smallest denomination in the series.
