Ancient Roman Silver Centenionali

Evidence from hoards suggests that the year 318 AD marked the demonetarisation of the outstanding coinage and its replacement by a new system, which included the large bronze ‘centenionalis’. Indeed, the size was in part designed to lend authority to this novel currency, but its circulation was short-lived (itself demonetised by 349 AD). It has been suggested that the name derives from its value: 100 denarii.
