Very rare antonian from Decius, combining the obverse legend IMP C M Q with the Genius on the reverse. The legend depicting the Genius was simplified on this coin and praised the Genius of Illyria, not the Genius of the Illyrian army, next to whom was still a banner. The military mark disappears from the reverse, and the Emperor honors his home province thanks to this procedure.
