Æ29 - Severus Alexander ϹΕΠ ΚΟΛΟ ΝΕϹΙΒΙ ΜΗΤ

Nisibis was among the easternmost cities to strike coins under Roman provincial authority, sitting just inside the frontier that Rome and Parthia — later Sassanid Persia — contested for centuries. The city held the status of colonia, granted under Septimius Severus after his Parthian campaigns of 195–198 AD, and that colonial rank is precisely why this bronze carries the abbreviated title visible in its legend. Under Severus Alexander the mint remained active, but output was modest; large bronzes from Nisibis are considerably scarcer than comparable issues from the Syrian or Asian provincial mints.
