AE centenionalis, Flavius Magnus Magnentius, AD 350 - 353

The obverse shows a two dimensional portrait technique that replaced that of the high relief technique that was produced in previous years. Here it still portrays the individual features of the emperor. Magnentius' portrait covers nearly the full surface of the coin, showing his flabby cheeks and full chin.
Obv. Magnentius right, DN. MAGNENTIVS AVG.
