Æ29 - Philip I ΚΙΑΝΩΝ

Cius, the Bithynian coastal polis at the mouth of the Ascanius river, issued bronze coinage under Philip I with conspicuous civic pride — the ethnic ΚΙΑΝΩΝ marking these pieces as products of a city that had long competed with Nicomedia and Nicaea for regional prestige. Philip's reign coincided with the celebration of Rome's millennial year in 248 AD, which prompted a surge of provincial bronze production across the eastern empire as cities sought association with the festivities. Whether Cius issued this piece in that context is not certain, but the chronology aligns closely.
