VICTORIA AVGGG (2nd reign, 476 / 491, 4th issue)

Bust of Zeno facing, cuirassed, wearing 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 referenced in the RIC X page 308, n°927. Source: Basel, Historisches Museum. I noted the legend breaks that we see most often. Same for the mark that can be CONOB, CONOR or CONOB / R. To confirm. Read this article detailing the subject of the marks CONOR and CONOB / R: https://www.all-your-coins.com/fr/blog/antique/romaines/analyse-de-la-marque-conor. 

Variant with jewels on the diadem.

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.
