Æ28 - Philip I ΝΙΚΑΙΕΩΝ

Philip I came to power in 244 AD by negotiating directly with Shapur I following the death of Gordian III — almost certainly by arrangement rather than accident. Nicaea, as one of the principal cities of Bithynia, struck civic bronzes under Philip in the usual pattern of provincial autonomy, the city's mint operating independently of the imperial system at Rome.

The reference VIII#19886 places this within the Sylloge Nummorum Graecorum or a related corpora framework for Bithynian civic issues, where die studies have shown considerable variation in module and fabric across Philip's short reign.
