His coinage includes both helmeted and unhelmeted portrait types. On this obol he is represented with the royal diadem rather than the distinctive helmet seen on some of his other issues. The reverse depicts the pilei of the Dioscuri, Castor and Pollux, accompanied by palm fronds, an important recurring motif on Eukratides' coinage.
