One of the first United States gold coins to use Roman Numerals was the 1907 Saint-Gaudens Double Eagle. The artist who designed this coin, Augustus Saint-Gaudens, lead an effort to revive the artistic aspect of United States coinage. He wanted to give our coinage a more 'classical' look and feel. The primary coins of the era were the Gold Aureus, the Silver Denarius, and copper coins of various sizes. Typically Roman coinage had an image of the emperor on the obverse. On the reverse deities like Mars the god of war, or Venus the goddess of love,– would adorn the coins. Roman ancient coins: the origin of numismatics. Ancient coin collections may have existed since the Roman Empire times. It is known that Augustus would give ancient kings’ coins, as well as foreign coins and tokens as gifts for the Saturnalia festivity.
