This denarius from the time around 116 BC was issued by the two moneyers Marcus Calidius and Quintus Caecilius Metellus Nepos. Their abbreviated names are given below the hooves of the horses on the reverse.
During the Roman Republic a board of three moneyers was in charge of the mint, the tresviri monetales. The office of a moneyer was one of the minor offices of the vigintisexviri, a college of twenty-six young magistrates. These posts served as stepping-stones for the cursus honorum, the sequential order of republican public offices.
The obverse of the denarius bears the head of Roma, the goddess and personification of Rome, wearing a winged Attic helmet. Behind her is the inscription ROMA, and below her chin the (ligated) mark XVI for the coin's value of 16 asses. The reverse depicts Victoria, the goddess of victory, on a two-horse chariot in full gallop.
