Nepotian

In AD 350, Magnentius revolted, murdered Constans and claimed the Western Empire. Nepotian (Flavius Julius Popilius Nepotianus Constantinus, nephew of Constantine I) did the same in Rome. On June 3, 350 CE Nepotian attempted to take control over Rome and proclaimed himself emperor. He challenged the usurper Magnentius and seized Rome with a small band of gladiators. After ruling for 28 days, he was defeated by Magnentius' general Marcellinus and killed on June 30, 350. Coin shown is extremely rare. VF, even hard brown surfaces. $6,400.

Nepotian managed to strike both gold solidi and bronze centenionalis coins at the Rome mint during his brief reign. Many of his coins, and certainly his gold, are museum pieces.
