    ORC1217 Caracalla, 5.7g ant. aEF

Caracalla, AR heavy antoninianus, (5.70g) ANTONINVS PIVS AVG GERM Radiate,
draped and cuirassed bust right. / VENVS VICTRIX Venus standing holding
helmet and scepter, captives at feet. RSC 608; RIC312c. Near EF, heavy
example.

The new denomination introduced by Caracalla was valued at two denarii. The
radiate crown symbolized the intended doubling, over the next largest
denomination, the denarius. In general, this issue weighs about 4.5 grams.
This is a very heavy example, the second heaviest example we have
encountered.
