The obverse of this small coin depicts a gorgoneion, the chipped off head of Gorgo. In Sicilian iconography, Gorgo's head was considered to have strong magical power, and was thought to fend off evil spirits. The gorgoneion was a frequent motif on coins, but also on temple and city walls, on weapons and on amulets. It can be seen on numerous Sicilian doors and houses until this day.
The reverse depicts an owl holding a lizard in its claws. Underneath the animals is a pellet to indicate the coin's value of 1 onkia.
