Æ28 - Philip I ΝΙΚΑΙΕΩΝ

Philip I's reign coincided with Rome's millennial celebrations in 248 AD, and civic mints across Bithynia were active producers of bronze issues throughout his five-year rule. Nicaea, as one of the most prominent cities in the province — perennially rival to Nicomedia for the title of first city of Bithynia — maintained a vigorous local bronze output under Philip, leveraging imperial coin portraits as much for civic prestige as for exchange.

The reference VIII#58775 places this within a well-documented but not exhaustively catalogued series of Nicaean provincials.
