From wildwinds:
http://www.wildwinds.com/coins/ric/...ntine/i.htmlCONSTANTI-NVS MAX AVG, rosette-diademed, draped, cuirassed bust right / GLOR-IA EXERC-ITVS, two soldiers holding spears and shields with two standards between them.
Standards have no drapery and very thin shafts with pointed tops instead of banners. Mintmark: TR dot P. RIC VII Trier 537.


These standards are the regular type, however. I can't find anything else with that mint mark.
