Diocletian Silvered AE Antoninianus. Lyons mint, 292-294 AD. Obv: IMP DIOCLETIANVS AVG, radiate, draped & cuirassed bust right Rev: IOVI AVGG, Jupiter seated left holding Victory on globe & scepter, I in ex. RIC 34, Cohen 169. Unlisted officina I, which is listed for RIC 33 but with a slightly different obverse legend. (RIC 34 has listed officinae of A, C and *U.) RIC 34 lists bust types of (A) draped, (C) draped & cuirassed, and (F) cuirassed. Cohen 169 says "draped or cuirassed" but I guess that also covers draped & cuirassed like this one.
