Æ24 - Trebonianus Gallus ΠΡΟΥϹΑΕΩΝ

Prusa ad Olympum was a mid-tier Bithynian city with enough civic ambition to maintain an active bronze coinage under the Severans and their successors, but production under Trebonianus Gallus was already winding down as imperial authorization for provincial bronze issues contracted sharply in the early 250s. His reign coincides almost exactly with the final gasps of the Bithynian civic series — within a few years of his assassination in 253, most of the region's municipal mints had gone permanently silent.
