This FEL TEMP was issued for Constantius II by Vetranio. What I find interesting is that the FEL TEMP galley type was most likely initially issued by Constans in reference to a visit he made to Britain in A.D. 343, and it seems he was celebrating some sort of a victory on these coins. Of course, when this coin was issued by Vetranio, Constans was dead, killed by troops under Magnentius.
