Æ27 - Antoninus Pius ΑΠΟΛΛΩΝΙΑΤΩΝ ΠΡΟϹ ΡΥΝ

Apollonia ad Rhyndacum, a small Mysian city on the river Rhyndacus, struck civic bronze under Antoninus Pius as part of the broader system of Greek imperial coinage — issues produced by provincial cities with imperial permission, typically funding local religious or civic obligations rather than imperial taxation. The mint was modest and output appears to have been limited; the city's coins from this reign are significantly rarer than those of neighboring Cyzicus, whose conventus administered the region.
