Æ - Antiochus IV

Antiochus IV of Commagene had one of the more turbulent relationships with Rome of any client king — restored to his throne by Caligula in 38 AD after his father's kingdom had been briefly absorbed into the province of Syria, he ruled for over three decades before Vespasian finally deposed him in 72 AD following accusations, likely politically motivated, of colluding with Parthia. His coinage spans that entire precarious stretch, issued by a kingdom that existed largely at Roman sufferance.
