tresviri auro argento aere flando feriundo (“the three men for casting and striking of gold, silver and bronze” )
An inscription from Ephesus recording (the first part) of the title from the 120s CE.
The title has been long known from coins.
Very nice illustrated specimens can be found in the Berlin collection.
A nice intro summary of the office of moneyer.
Another nicer epigraphic example from Ephesus!
