RIC VII, NICOMEDIA 90, CONSTANTINE I, ENGRAVER'S ERROR [RETROGRADE OBVERSE] [IRREGULAR COIN]

OBVERSE	GVASVNIT-NATSNOC [GVA SVNITNATSNOC (retrograde)]; head l., laur.
REVERSE	PROVIDEN-TIAE[AVGG] [PROVIDENTIAE AVGG]; camp gate, two turrets, no doors, star above, varying number of stone layers. SMNΓ in exergue.
NOT IN RIC	ENGRAVER'S ERROR. Coin similar to NICOMEDIA 90 except for retrograde obverse. Apparently an engraver's error. But note also dots in the top row of stone layers and diagonal lines near doors - decoration not attested for Nicomedia. Probably an ancient imitation.
