Obverse CO(NSTAN)TINVS IVN NOB C; Laureate bust right, draped and cuirassed Reverse (GLOR)-IA EXERC-ITVS (the glory of the army); two soldiers helmeted, standing facing each other, reversed spears in outer hands, inner hands on shields resting on ground, between them two standards; CONST in exergue (Constantinople mint, second officiana)
Another nice coin :thumb: Your ID is spot on except that the mint CONST is actually Constantina (now known as Arles) in France . It was allegedly Constantine The Great's favourite place so he had it named after him.:smile This is a useful link find Roman mint names..... http://www.forumancientcoins.com/numiswiki/view.asp?key=Roman%20Mints Tony
