RIC VII, NICOMEDIA 154, CONSTANTINE I, UNLISTED OFFICINA B

OBVERSE	CONSTAN-TINVSAVG [CONSTANTINVS AVG]; head r. with plain diadem decorated with pearls.
REVERSE	PROVIDEN-TIAEAVGG [PROVIDENTIAE AVGG]; camp gate, two turrets, no doors, star above, varying number of stone layers. SMNB in exergue.
NOT IN RIC	UNLISTED OFFICINA - B. Diadem is significantly different from threefold pearl diadem on NICOMEDIA 153 and from rosette-diadem with small end-rosette on NICOMEDIA 155 (however, the latter may be disputable). Therefore, it should be regarded as a plain diadem decorated with pearls attested for NICOMEDIA 154. RIC lists for this type only officinae A, Є and S.
