Roman Coins (Denarius)
An illustration of a roman coin (denarius). The left side represents the laurel-crowned head of Titus. The right side depicts a female sitting underneath a palm tree with helmets behind her. The Roman currency system included the denarius after 211 BC, a small silver coin, and it was the most common coin produced for circulation but was slowly debased until its replacement by the antoninianus.
