Aurelian AE Antoninianus. 

IMP AVRELIANVS AVG, radiate, cuirassed bust right (wide upper body).
IOVI CONSER, Emperor standing right, holding sceptre and 
receiving globe from Jupiter, holding sceptre. 
Officina letter B in ex. 

RIC 394, unattributed mint; Sear5 11542v.

This officina letter on this reverse type is also known on
RIC Rome 48, but the wide upper body is not known for the 
Rome mint, but rather from Siscia or Milan.
In addition this type is also often sold as RIC 129, but that
is incorrect, as they use only P, S, T and Q as officina 
letters, not B.
