Constantine I, 307/310-337. Follis (Bronze, 24 mm, 3.35 g, 12 h), Rome, 314. IMP CONSTANTINVS P F AVG Laureate, draped and cuirassed bust of Constantine I to right. Rev. MARTI CO-NSERVATORI / R - F / R✱P Mars standing front, but slightly turned to right, head to right, holding inverted spear in his right hand and placing his left on shield set on the ground. RIC -. Extremely rare. Minor traces of corrosion, otherwise, about extremely fine.



This example with Mars standing front and looking right is exceedingly rare. RIC only lists Mars standing left, looking right. New material reveals that the engravers produced all possible variations: Mars standing either way and looking either way.
