Interesting fact

The Antoninianus coin, which was issued during the reign of Diocletian (284-305 AD), was a significant departure from previous Roman coins in terms of its design and metallic composition. It was the first Roman coin to feature a portrait of the emperor on one side and a personification of the state (in this case, Salus, or "Salvation") on the other. This innovation marked a shift towards a more humanized representation of the emperor and the state, and paved the way for the more naturalistic and detailed portraits that would become common in later Roman coinage.
