A coin of Constantius as Caesar, Heraclea 133, but with an interesting engraver's error, with an extra N added to make it read as if it were Constantine II. There is little doubt it is simply an engraver's error and not an unlisted legend; apart from the incongruity of FL IVL for Constantine II, Heraclea at this time consistently had Constantine II with a B5 bust (cuirassed), and Constantius with a B4 bust (draped and cuirassed) i.e. as this coin. Weight is 2.93g, diameter approximatey 17 mm
