@John Anthony... It's an AE3 from Cyzicus of Licinius II, who served as Caesar under his father Licinius. Unfortunately for the Licinii, the second war fought with Constantine ended up in their defeat and executions. Obverse: Draped and cuirassed bust of Licinius right. DN VAL LICIN LICINIVS NOB C Reverse: Jove standing left with cape, holding Victory in his right hand. JOVI CONSERVATORI CAESS Please share your coins of the Licinii. (ex the @dougsmit collection). I think it's interesting the the prefix DN was used, whereas their earlier coinage featured IMP.
