Caracalla Ae As
Obv:- ANTONINVS PIVS AVG GERM, Laureate, draped and cuirassed bust right
Rev:- P M TR P XVII IMP III COS IIII P P - S C, Mars, helmeted in military dress, cloak over left arm, standing front, head left, right knee slightly bent, holding branch raised in right hand and vertical spear in left hand. Items on ground. I cannot really make them out but at magnification they look like helmet on left, cuirass between legs and spear resting on shield.
This seems to generally match RIC 532b, which cites Cohen 260. RIC 532a is the same reverse type with a Laureate head right. BMCRE does not include this type with this bust but does include the type in the notes to BMCRE 268. BMCRE 268, which is the Laureate head type is described as right foot on helmet with cuirass? to right.
