Persuaded to take the purple as a tactical move to limit the damage of Magnentius' Western usurpation, Vetranio fulfilled his duty, remained loyal to Constantius, abdicated orderly after nine months and lived thereafter in comfortable retirement. His coins remain predictably scarce today, and their military reverse themes reflect the context of this rule.
