It is attributed as: Commodus AE24 as. Obv: Laureate, draped and cuirassed bust right. L AVREL COMMODVS AVG. Rev: Victory advancing to left, holding wreath and palm, TR P II IMP II COS PP around, S C across fields. RIC 569. 177AD. But when I looked up RIC 569, it was not the same coin. In fact, I can't find an as with a radiate head and a Victory reverse at all. There is a dupondius, RIC 1474, that has the radiate head right and Victory reverse. Also it has a completely different legend on both sides. Commodus AE Dupondius. L AVREL COMMODVS AVG TR P IIII, radiate head right IMP III COS II P P S-C, Victory advancing left bearing wreath & palm. My coin is 10.80g and about 24mm. Could it just be a smaller dupondius that is lighter due to wear and being on a smaller flan? Or am I missing something completely obvious?
