Mithridates VI of Pontus
The first coinage of Ariarathes IX of Cappadocia show the portrait of the young king with features that are reminiscent of earlier Cappadocian kings. The coins are of typical Cappadocian style, with Athena on the reverse and his title Eusebes, from his full title Eusebes Philopater. Soon after the coins started to bear a portrait which was much closer to that of his father Mithridates VI of Pontus, Dr. Imhoof-Blumer suggests that this portrait is actually the head of Mithridates VI of Pontus himself, and not that of his son Ariarathes IX.
