 This coin's reverse legend ('by this sign you shall conquer') refers to the divinely
  inspired vision of Constantine the Great before the Battle of the Milvian Bridge, and
  struck by Vetranio for himself and in the name of Constantius II. Vetranio eventually
  handed over his legions to Constantius II at Naissus, afterwards withdrawing into an
  honorable retirement at Prusa in Bithynia.
