Æ24 - Vespasian ΕΠΙ ΜΑΡΚΟΥ ΠΛΑΝΚΙΟΥ ΟΥΑΡΟΥ ΑΝΘΥΠΑΤ (Υ)

Cius, the ancient Bithynian port at the head of the Gulf of Mudanya, retained the right to strike civic bronze under Roman provincial administration, and the lengthy proconsular legend naming Marcus Plancius Varus reflects the Greek east's practice of dating issues by the sitting governor rather than regnal year alone. Plancius Varus is attested as proconsul of Bithynia-Pontus under Vespasian, placing this strike within a narrow administrative window.

The city had a complicated history with civic autonomy, having been refounded by Prusias I of Bithynia in the early second century BC — briefly renamed Prusias ad Mare before reverting to its older identity under Roman rule.
