Nummus - Galerius as Caesar Large head, short neck, MAXIMIANVS NOB CAES, GENIO POPVLI ROMANI, Londinium

Struck at the London mint during the final years of Galerius's tenure as Caesar under Diocletian's Tetrarchy, this issue falls within the period immediately preceding the Great Persecution of Christians — an imperial program Galerius is widely credited with instigating and which formally began in 303 AD with the destruction of the church at Nicomedia. The London mint was among the westernmost production points in the tetrarchic system, operating under the administrative authority of Constantius I in the same years he was campaigning against the Picts beyond Hadrian's Wall.
