This section of Numismall.com contains coins of Licinius I, Licinius II and their relatives, covering the period from 307 to 324 AD. The Roman Empire, spanning much of Europe, North Africa and the Middle East, produced thousands of different types of coins throughout its history. Each of the Emperors and many of the usurpers minted coins showing their portrait and naming them, making the Roman coins very rich in history. Roman currency for most of Roman history consisted of gold, silver, bronze, orichalcum and copper coinage. From its introduction to the Republic, during the third century BC, well into Imperial times, Roman currency saw many changes in form, denomination, and composition. Roman Imperial coinage remains one of the most popular collecting areas in numismatics.
