Appears to be overstruck on a Syracusan litra, Athena/Hippocamp (Calciati 1986, p. 87, n° 42), with a trace of the hippocamp's tail visible on the pileus. Often attributed to Skylletium in Bruttium on the basis of the Skylla on the reverse, this type has been found in excavations in Locri and in north-central Sicily, and as is the case with this coin, is often times overstruck on a Syracusan litra
