Good afternoon, Saw this coin for sale, quite worn Vot V type. The seller said it's a Constantius II (and quite adamant) but I can't find a match. First, all Constantius II Vot V have a different reverses (afaik) and this reverse type suits for other rulers. What strikes me is the cross sign over VOT, I haven't found this design of the wreath anywhere except for Valens siliqua Antioch RIC IX 33b2 but that looks like a real cross. I am not convinced that on this coin that is a Christian symbol but nevertheless puzzles me.
here's an example for Jovian from Alexandria, though your mintmark looks different, but maybe it is ALEB, with LE weak.
Tesorillo is offering us four possibilities , I will say Iovianus ? The bold letters I think are visible DN IOVIAN - VS PF AVG , the portrait style match. http://www.tesorillo.com/aes/062/062i.htm
