Æ - Prusias I or II

Bithynia's royal bronze coinage presents a persistent attribution problem: the two Prusias kings reigned across nearly a century, and the iconographic and epigraphic conventions shifted gradually enough that clean separation remains contested. Recueil général and von Aulock have landed on different conclusions for overlapping types. Prusias I, who ruled roughly 230–182 BC, built his kingdom partly through calculated neutrality during Rome's wars with Macedon and then pivoted opportunistically — harboring Hannibal after Zama until Roman pressure forced Hannibal's suicide at Libyssa around 183 BC.
