This coin is not listed in RIC, but only because of an error. RIC lists Siscia 81 with a D2 bust (plain helmet), but this coin actually has a D6 bust (laureate helmet) same as all Constantine I Siscia VLPP's without spears; so this coin should actually be RIC VII Siscia 81.
Constantine I
A.D. 319
IMP CONSTANTINVS AVG; laureate helmet and cuirassed bust right.
VICT dot LAETAE PRINC PERP; two Victories stg., facing one another, together holding shield inscribed VOT PR on altar.
In ex. dot epsilon SIS dot
RIC VII Siscia 81
