Abt. EF, slight doubling on the reverse, good style portrait, substantial remaining silvering and reflective surfaces.  London folles are not often seen with so much silvering. Constantius was responsible for retaking Britain from Allectus. Cloke & Toone comment that the portraits of Constantius are much more likely to be of better, more refined style than those of the other tetrarchs. 

Collection : The Tetrarchy to the defeat of Maximinus 313 AD.
