The coinage of Emperor Rome (330-348) reflects the changes in the financial situation of the Roman Empire. In the 330s, after moving the capital of the empire to Constantinople, Rome significantly reduced the amount of coinage. This move was probably a consequence of the empire's economy going through hard times. However, the amount of coinage began to increase again in the 340s, which indicates the economic recovery of the empire. Rome's coinage was made in the following denominations: Aureus: gold coin, weight 4.5 grams, Solidus: gold coin, weight 4.1 grams, Argenteus: silver coin , weight 3.6 grams, Follis: bronze money, weight 10 grams. The aureus and solidus were the highest value coins and were mainly used in official payments. Argenteus is the most valuable of the silver coins and was also used in trade. The follis was the lowest value money and was used in everyday life. The most characteristic motifs of Rome's coinage, the obverse usually featured a portrait of the emperor. Symbols of the emperor's reign were visible on the back, such as the imperial diadem, the labarum (cross banner) or the imperial throne. Coins from the Roman era are still valuable numismatic rarities today.
