Æ29 - Philip I ΙΕΡΑΠΟΛΕΙΤΩΝ Κ ϹΑΡΔΙΑΝΩΝ ΝΕΩΚΟΡΩΝ ΟΜΟΝΟΙΑ, ΠΥΘΙΑ, ΧΡΥϹΑΝΘΙΝΑ

Hierapolis and Sardis struck homonoia coinage — alliance issues jointly celebrating two cities — as a form of diplomatic currency, advertising civic harmony to Roman administrators and rival poleis alike. This piece commemorates three festival cycles: the Pythia, the Chrysanthina, and the broader homonoia games, suggesting an unusually elaborate ceremonial context for the alliance. The Chrysanthina, a flower-crown festival attested primarily at Sardis, is rarely referenced on bronze provincial issues outside that city's own coinage.

Philip I's reign provided fertile ground for such civic posturing; cities across Asia Minor competed aggressively for neokorate status and festival recognition from Rome during the 240s.
