The coin in question dates back to the Roman Empire, specifically from the period between A.D. 117-138. Unfortunately, its exact place of origin is unknown.
During this time, Roman emperors recognized the significant value of coinage as a tool for propaganda. Coins were circulated widely, and they bore ever-changing inscriptions on their reverses, which allowed the government to convey its image and accomplishments to people throughout the vast empire. This medium of communication was under complete governmental control. The personifications depicted on these coins, such as Fortuna in this instance, often symbolized various virtues of the emperor or the good fortune of those fortunate enough to live under his rule. Here, Fortuna is represented with a horn, symbolizing prosperity, emphasizing the positive aspects of the emperor's reign.
