Latest since the year 150 BC, the issue of Roman coins was the department of a college of three moneyers, the 'tresviri aere argento auro flando feriundo, the 'three men for the striking and casting of bronze, silver and gold.' These men were not mere workers, but officials responsible for the whole process, from acquiring the coin metal over designing the coins to striking and issuing them.
This denarius was minted under the supervision of Claudius Coelius Caldus in the year 104 BC. On the obverse is the goddess Roma, the reverse shows the goddess Victoria in a Biga. Underneath is the inscription CALD for the moneyer and the mint control mark A.
