RIC VI, ROMA 351a, CONSTANTINE, OFFICINA Q [CONFIRMATION], ENGRAVER'S ERROR

OBVERSE	IMPCONSTANTINVSPFAVG [IMP CONSTANTINVS P F AVG]; bust r., laur., dr., cuir., seen from rear.
REVERSE	SPQROP-RINCIPI [S P Q R O (sic!) PRINCIPI]; legionary eagle facing l. between two vexilla. RQ in exergue.
NOT IN RIC	[CONFIRMATION]. RIC lists this type with remark "Confirmation required". Note that attribution of this bust type could be disputable: CORRIGENDA, VOL. VI, BUST TYPES SEEN FROM REAR. But note also interesting variety of rev. legend: S P Q R O PRINCIPI instead of S P Q R OPTIMO PRINCIPI. Apparently an engraver's error.
