Author of a law regulating coinage, under which the quinarius was issued as a victoriatus (Plin. NH 33.46; Grueber, CRRBM 1.158). It is not certain that the bill was tribunicial, and its author may perhaps be identified with M. Claudius Marcellus (RE no. 226). See Niccolini, FTP 419f. (Broughton MRR I)
