Solidus - Magnentius VICTORIA AVG LIB ROMANOR, Treveri

Magnentius seized power in January 350 by murdering Constans at a banquet in Helena (modern Elne), making him the first Western usurper in decades to hold the throne long enough to build a coherent coinage. The Trier mint — one of the great production centers of the late empire — struck solidi for him throughout his three-year reign, and this issue was almost certainly produced under pressure of active military expenditure. His war against Constantius II culminated at Mursa Major in 351, one of the bloodiest battles of the fourth century, after which Magnentius never recovered militarily.

He died by suicide in August 353 at Lugdunum. Coins bearing his name were systematically demonetized after Constantius reasserted control.
