I have been trying to figure out the attribution on this Constantius II. I purchased it because I really like the detail of bust, fallen horseman, and the guy with the spear but the exergue lettering is rough. I also like the surfaces It is 22mm and 4 grams. I am fairly sure the legend is the typical DN CONSTAN-TIVS PF AVG / FEL TEMP RE-PARATIO. Maybe CT's local-yokel FH experts can help?
