Licinius II. AE3. 320 AD. 

LICINIVS-IVN NOB C, laureate bust right
CAESARVM NOSTRORVM around VOT (centering dot) V, within wreath,
 star in badge at the top of the wreath, Delta SIS in ex. 

RIC VII Siscia 155, rated R1. 

Space appears to have been made for a symbol after the SIS, 
e.g. the star of issues of the same series, which instead
 appears in the badge. The bust type, showing shoulders, is
 also unusual.
