Æ - Prusias I or II

Bithynia's Prusian dynasty occupied an awkward position throughout the Hellenistic period — nominally independent, perpetually squeezed between Pergamon, Pontus, and the encroaching Romans, and tactically shifting alliances to survive. Prusias I famously sheltered Hannibal after the Carthaginian general fled Rome's reach following Zama, a decision that eventually cost him Roman goodwill. Prusias II took the opposite approach, personally humiliating himself before the Roman Senate in 167 BC, earning the nickname Philoromaios — friend of the Romans — while his own son Nicomedes conspired with Rome to depose him.

Attribution to one king or the other remains unresolved without die study against dated parallels.
