Æ21 - Septimius Severus ΑΔΡΙ ΠΕΤΡΑ ΜΗΤ

Petra retained its civic coinage rights well into the Severan period, a privilege tied directly to the city's status as a metropolis of Arabia Petraea — a designation formalized under Hadrian and jealously maintained. Severus, consolidating eastern support during his war against Pescennius Niger, had strong incentive to affirm such honors in provincial cities along the Arabian frontier.

The metropolis title in the legend is the detail worth noting: not all Arabian civic issues under Severus carry it explicitly, making the epigraphic formula here a marker of civic rank, not decoration.
