He and C. Norbanus (see below) are termed Pr(aetores?) on gold coins issued in 44 or 43 (pr(aefecti), Grueber, CRRBM 1.552f.) by decree of the Senate. As the list of Praetors for 44 is so completely known, I place them in 43. See Bahrfeldt, R6m. Geldmünzpragung 41f., and Groag, RE 17.1.1271, on Norbanus. (Broughton MRR II)
Praetor 44 or 43. See MRR 2.338. Crawford dates his coins with Norbanus Flaccus to 43 (RRC 1.500, no. 491). See below on Norbanus Flaccus (9a).
