All coins in the Decrees and the Edict were valued according to the "denarius", which Diocletian hoped to replace with a new system based on the silver "argenteus" and its fractions (although some modern writers call this the "denarius communis", this phrase is a modern invention, and is not found in any ancient text). The "argenteus" seems to have been set at 100 "denarii", the silver-washed "nummus" at 25 "denarii", and the bronze radiate at 4 or 5 denarii. The copper laureate was raised from 1 "denarius" to 2 "denarii". The gold "aureus" was revalued at at least 1,200 "denarii" (although one document calls it a "solidus" it was still heavier than the "solidus" introduced by Constantine a few years later).
