Follis - Galerius GENIO POPVLI ROMANI - Smaller Head, Strike as Caesar under Diocletian, Siscia

Galerius struck this issue at Siscia as Caesar under Diocletian's tetrarchic reorganization, a system formalized in 293 AD that divided imperial authority across four rulers while maintaining the fiction of collegiate unity. The Siscia mint was one of the most active in the western Balkans precisely because of its strategic position on the Sava River, supplying coinage to frontier armies along the Danube limes. RIC VI 90b distinguishes this piece by the smaller head variant — a die modification made mid-production, likely reflecting a workshop change rather than any deliberate political signal.
