Tetras

Piakos was a small Sikel settlement in the interior of Sicily whose coinage output was extremely limited, making any survival a minor archaeological event. The tetras — a bronze denomination equal to three onkiai — was the workhorse fractional unit of Sicilian bronze coinage, but issues attributable to Piakos specifically are rare enough that the CNS catalogues only a handful of distinct types. The settlement itself effectively disappears from the historical record within a generation of this coin's striking, likely absorbed or destroyed during the turbulent Carthaginian campaigns of the early fourth century.
