It's supposed to say VABALATHVS V C R IMP D R over the portrait of Vabalathus (the laureate bust) and it says IMP C AVRELIANVS AVG on both sides. Here's my non-error version: Vabalathus, AD 270-272 and Aurelian, AD 270-275. Roman billon antoninianus, 3.58 gm, 20.4 mm, 5 h. Antioch, late AD 270-spring 272. Obv: VABALATHVS V C R IMP D R, laureate, draped and cuirassed bust of Vabalathus, right. Rev: IMP C AVRELIANVS AVG, radiate and cuirassed bust of Aurelian right; officina mark Є below.
