Æ20 - Valerian and Gallienus COL G IVL H PAR

Parium was one of the oldest Greek colonies on the Propontis, but by the joint reign of Valerian and Gallienus it had long held Roman colonial status — a distinction the city advertised aggressively on its civic bronze. The abbreviated title COL G IVL H PAR compressed centuries of accumulated honorifics into a handful of letters, the "Hadriana" element reflecting a grant likely tied to Hadrian's known favoritism toward Propontic cities during his 123 AD tour of the region.

Civic bronze production at Parium effectively ceased after Gallienus, making this among the final issues from the mint before the broader collapse of provincial coinage in the Greek East during the 260s.
