Drachm - Ariarathes IX Eusebes Philopator

Ariarathes IX ruled Cappadocia as a client of Mithridates VI of Pontus — his own father, who had installed him on the throne after disposing of the previous king. The arrangement was never stable. Rome repeatedly intervened in Cappadocian succession disputes throughout this period, and Ariarathes IX was eventually killed fighting against his own father's forces around 87 BC when Mithridates moved to absorb the kingdom directly, just before the First Mithridatic War with Rome reached its peak intensity.

HGC 7, 845 treats this type as scarce, reflecting a reign defined more by political manipulation than independent authority.
