1. Marcus Aurelius as Caesar denarius. Assuming that the reverse reads as COS II I believe it may be from 145 CE when Marcus was only 24. First coin of the Five Good Emperors for my collection. 2. Gordian III Antoninianus 241 CE. At the age of 16 when this coin was minted Gordian was already halfway through his reign as emperor (not that he would have known!). Auction house gave a reference of RIC 93. Does anyone else have coins of young emperors to show? (Or coins minted for younger men yet to be emperors?).
