Nummus - Valentinian I GLORIA ROMANORVM; Lugdunum

RIC IX 20 belongs to the post-reform bronze coinage reorganized under Valentinian I and Valens after 364, when the empire was formally divided between the two brothers at Mediolanum. The Lugdunum mint — modern Lyon — was among the more productive western facilities during this period, supplying bronze to a military establishment under near-constant pressure from Alamannic incursions across the Rhine frontier, campaigns that consumed Valentinian's attention until his death from a burst blood vessel while angrily receiving a Quadic embassy in 375.
