Æ18 - Domitian ΠΡΟΥΣΙΕΩ

Cius, the Bithynian port city at the mouth of the Argonauts' legendary harbor on the Propontis, issued civic bronzes under Domitian as part of a broader pattern of Greek eastern cities maintaining local coinage alongside the imperial system. The city's name appears in the genitive as ΠΡΟΥΣΙΕΩΝ on issues from this period — reflecting its refoundation as Prusa on the Sea by Prusias I of Bithynia in the early 2nd century BC, a renaming that complicated the city's identity for centuries.
