Interesting fact
The Aureus was a gold coin used in ancient Rome, and the one , issued during the reign of Trajan (98-117 AD), features an interesting design on its reverse side. It depicts the Roman goddess of victory, Victoria, standing on the prow of a ship, holding a trophy and a palm branch. This design was meant to symbolize the Roman Empire's military conquests and naval power. The coin's design and the use of gold, which was a valuable and prestigious metal at the time, reflected the wealth and power of the Roman Empire during Trajan's rule.
