Silver antoninianus with a radiate crowned portrait of Trajan Decius facing left, and the legend IMP C M Q TRAIANUS DECIUS AUG. The reverse shows Decius riding a horse to the left, although it appears to us more like a camel. An alternative suggestion would be that the emperor was taking part in the first recorded game of polo (this coin is mint!). The reverse legend reads ADVENTUS AUG, meaning the arrival of the emperor, in this case almost certainly in Rome, and probably in 249 AD.
