This coin is a little worse for wear; but it is not in RIC. This reverse type for Constantine I is recorded as cuirassed only; while this coin is cuirassed and draped. It should come after RIC VII Rome 146. It is similar to bust type D5 (laureate helmet, draped and cuirassed) except this coin has what looks like a plain band (which might just be a riveted band), but definitely not laureate, as you can clearly see that there are no laurel ties trailing from behind. This is the auction photo and a new photo Constantine I A.D. 318-9 19mm 2.9g CONSTA-NTINVS AVG; draped and cuirassed bust right, with banded helmet. ROMAE AETERNAE; Roma std. r., shield in lap inscribed X/V, across fields P-R. in ex. RQ RIC VII Rome –- for comparison, here is a later coin with the normal cuirassed only bust and here is a Rome campgate with a laureate helmet, versus a banded helmet.
