During his reign Constantine I made reforms to the monetary system that started with the introduction of a new gold coin, the solidus, and was followed by the re-establishment of pure silver coinage in place of the debased coins in circulation. This example, weighing 3.50g, is classified as a miliarense, which is the name applied to the pure silver coins of similar weight struck after 325. It could, therefore, be an early prototype as it was struck during the four year period that Constantine I used the city of Sirmium as his capital before moving to Nicomedia in AD 324.
