Coinage of ancient Sicily featured some peculiarities that could not be found elsewhere in the ancient world. One of these oddities was that small coin denominations were indicated by marks of value. The three pellets beneath the hooves of the bull on the obverse of this coin account for 3 onkiae. The coin was called tetras – a quarter of a litra. It was minted in the city of Gela, as the inscription indicates. The bull and the head of the horned river god are typical for Gela.
