This type is the first appearance of Octavian's portrait on a coin - a portrait which would come to dominate the obverses of Roman coins for decades to come. Interestingly, this portrait is a little different than most Octavian/Augustus portraits, not just because of the younger appearance but also because of one minor detail you can see on the chin: the beard. Unlike his later clean-shaven portraits, Octavian retains his beard mourning the assassination of Julius Caesar here, but as this type often comes worn you rarely get that detail which makes this coin particularly special. The reverse likely represents the statue awarded to Octavian after his victory at Mutina, where Octavian arose as an equal to Antony.
