While these coins of silver were historically struck using dies of bronze or iron, there is evidence that the dies themselves were cast rather than carved to provide a more consistent and uniform coin. There have also been discovered clay molds of coins and theories that these molds could have been used for the casting of dies or coins.

The obverse of this denarius features the visage of Master Tiberivs Ivlivs Rvfvs Primvs with his name using the standard documented coin abbreviations:
TI = Tiberivs
IVL = Ivlivs
RV = Rvfvs
PRIMIS = Primvs
The reverse of the coin features the registered badge: A lightning bolt palewise between and conjoined to two bees with a laurel wreath superimposed.

The master was etched on copper and the final denarius was sand cast in pure silver.

Copies cast in pewter.
