The Antoninianus

Antoninianus of Caracalla depicting Sol the sun god

This Roman silver coin was introduced by Caracella in 215. It was meant to be worth two denarii but even at its conception only had one and a half times the silver.

The debasement of the coinage persisted through the next century of Roman rule and later issues of the coin were in base metals. The coin was abandoned by the end of the third century. Large numbers of contemporary counterfeits were produced. On the obverse of the coins the emperor is usually wearing a radiate crown.
