RIC VI, ROMA [before 1], DIOCLETIAN, UNLISTED ISSUE [IOVI CONSERVAT AVGG]

OBVERSE	DIOCLETI-ANVSPFAVG [DIOCLETIANVS P F AVG]; head r., laur., fold of drapery on far shoulder.
REVERSE	IOVICO-NSE-R-VATAVGG [IOVI CONSERVAT AVGG]; Jupiter stg. l., chlamys hanging behind, r. holding thunderbolt, l. leaning on sceptre. PROM in exergue.
NOT IN RIC	UNLISTED ISSUE. The mark PROM was already known to Cohen (cf. Cohen, vol. VI, p. 517, no. 254) and to Voetter (cf. Sammlung Bachofen von Echt, Wien 1903, p. 133, no. 2329). Also Percy H. Webb - the author of RIC V - mentioned that "the exergual mark PR is common on aurei of the new style before and after the Reform. PROM appears after that event" (RIC vol. V, part II, p. 214). Unfortunately, entire AV series with PROM m.m. was omitted in RIC VI, in error. Note that so far two different rev. legend breaks are attested: O-NSE-R-V and O-NSER-V, which could make in RIC two separate entries (cf. TREVERI 802 and 807 or SISCIA 61 and SISCIA 62). Listed in Depeyrot (p. 83, no. 9/2; rev. legend breaks O-NSER-V). Should be listed in RIC before ROMA 1.
