Antoninianus Coins
The clearest modern example of the evolution of the antoninianus coin is the American "Johnson Sandwich" quarter. Created in 1965, the sandwich quarter retained the traditional portrait of George Washington while replacing a considerable portion of the coin's high silver content with cheaper copper alloys (turn a recent quarter on its side to see the sandwich). Originally issued by the emperor Caracalla in 215 AD, the antoninianus was originally described as worth approximately 2 denarii. Inherent worth in terms of silver continued to decline, however, until by the end of the third century AD, the antoninianus had become a bronze coin coated with a thin wash of surface silver. Coins available to modern collectors may display only traces or no indication at all of the fragile silver wash. The antoninianus, along with the already defunct denarius, ceased to be minted with the currency reforms of Diocletian.
