Bust of Romulus Augustus facing, cuirassed, wearing a helmet with crest and a pearl diadem. Holding a spear passing behind his head with the right hand and a decorated shield with a horseman slaying an enemy, with the left hand.
An angel standing left, holding a long latin cross decorated with jewels. Behind her on the right, a star.

Coin illustrated in the RIC X, plate 72, n°3407, source: museum of Turin.
As noted in the RIC X, this coin shares the same obverse die as the RIC 3401.
On the reverse I noted ''Angel'' in the description. We can also say that this is Victoria but the image of the victory at that time had indeed become that of an angel symbolizing the Christian victory.
The two dots noted on the right of the mark below, are positioned after AVGGG. The star is positioned above the letter M.
