On the reverse of this silver tetradrachm dated to the time of the Bithynian King Nikomedes I (280-250 BC), a warrior female goddess, perhaps Bendis, is depicted seated on boulder. She wears a short chitoniskos tied in her waist that leaves uncovered the right arm. She holds two spears in her right hand (that is why she is also called Bendis “Dilonchos”, δύο λόγχες, two lonches/lances) and a sword in its scabbard with her left. In front of the boulder, where she sits, there is a round shield richly decorated, and behind it a dead tree branch. There are also the inscription ΒΑΣΙΛΕΩΣ ΝΙΚΟΜΗΔΟΥ (by the King Nikomedes), the monogram ΙΔ and a winged Nike to the left. On the obverse, there is the portrait of King Nikomedes.
