I think that is AE 3 to Licinius I Licinianus (308-324) but I don`t 100 % sure, because the picture is little bad.
To Reverse is Jupiter with eagel in left and with Victory in his hand.
The coin yard is Nikomedia (SMNA) with oficina first app. A.
In right XIII, maybe is year to coin app. 321, or this is some of coin refform to Licinius to 313, I don`t sure for this
