Who is face is on the denarius?

Answer 1

There were many different people whose faces were on the denarius.

In republican times, the face was usually a mythical or symbolic person, such as a portrait of the Genius (or Personification) of Rome, or one of the gods or goddesses, such as Ares, Ceres, Juno, and many others. There was government offices of mint manager, held by two people at a time, and these was filled each year with new people. Each person was allowed to pick a design, and so there were many designs.

The actual person whose face appeared on a denarius was Julius Caesar. Marc Antony's face also appeared, as did a few others of lesser importance, such as Marc Antony's brother's. Once the Empire started, most of the people portrayed were emperors, members of the families of emperors, or people especially honored by emperors for some reason. The denarius became less important as a coin after the beginning of the third century, and disappeared about the beginning of the fourth.
