Tetras

Ziz — the Punic name for what the Greeks called Panormos, modern Palermo — operated as a Carthaginian administrative center in northwestern Sicily, and its coinage was closely tied to the military and commercial needs of Carthage's Sicilian campaigns. The tetras, worth three onkiai in the Sicilian bronze standard adapted here to silver, is among the smallest denominational divisions struck in the western Greek world. At 0.20 g, production tolerances would have been punishing.
