I can't quite figure this one out. The closest I have found is RIC VII 236, but then again I only have wildwinds to use as a reference.
CONSTANTI-NVS MAX AVG, rosette-diademed, draped, cuirassed bust right / GLOR-IA EXERC-ITVS, two soldiers with spears and shields; two standards between them. PLG in ex. The two standards are different than the 236 example on wildwinds.
