Æ - Prusias I or II

Bithynia's royal bronze coinage presents an attribution headache that has occupied specialists for decades — the reigns of Prusias I (c. 230–182 BC) and Prusias II (c. 182–149 BC) share enough iconographic and epigraphic overlap that confident assignment often rests entirely on die study rather than any single diagnostic feature. Prusias I secured his kingdom partly through shrewd diplomacy with Rome and famously harbored Hannibal after Carthage's defeat, a decision that ultimately cost him Roman goodwill. His son Prusias II proved considerably more servile toward Rome, earning the nickname "the Hunter" from his own subjects — not affectionately.
