Recently, we found these coins that date back to the 2nd/3rd centuries. Two of the originals (which we cast in sterling silver) are of Antoninus Pius (the goddess Fortuna on the reverse) & Septimius Severus (on the reverse is an elephant which represented sport). The third is a coin with the image of Vesta; the virgin goddess of the hearth, home & family (on the back is Diva or Divine Faustian, Empress and wife of Antoninus Pius) which we cast in bronze. All mounted on a 24" (60 cm) sterling silver chain.
