Interesting fact

One interesting fact about this coin is that it was issued during the reign of Diocletian, who was the first Roman emperor to introduce a new system of coinage that was based on the silver argenteus, a coin that was equal in weight to the old denarius but had a higher silver content. This new system helped to stabilize the Roman economy and paved the way for the introduction of the solidus, which became the standard coin of the Byzantine Empire.
