This highly unusual and pictorially attractive reverse type honors the important mint city of Siscia in the province of Pannonia Superior. The city goddess is seated between two river gods, representing the Savus and the Colapis, at the confluence of which the city stood. It repeats a type originally appearing on the coinage of Gallienus, who used it to celebrate his opening of the Siscia mint.
