Prusias ad Hypium — modern Konuralp in northwestern Turkey — was a Bithynian city that had passed into Roman provincial administration in 74 BC following the bequest of Bithynia by its last king, Nicomedes IV. Under Trajan, civic bronze coinage of this type was produced locally rather than at an imperial mint, a practice that gave Bithynian cities considerable latitude in expressing civic identity within Roman rule. The letters Π-Ρ flanking the field are an abbreviation of the city's name, a convention used to distinguish issues across a region where multiple mints struck similar civic bronzes simultaneously.
