Otto Seeck and Karl Pink, in "Die Goldprägung des Diocletianus und seiner Mitregenten," NZ 64 (1931), pp. 57-58," correctly hypothesized the marks on this aurei series designate the weight standard of N issues (1/50 to the Roman pound, 6.40 gm standard), O issues (1/70=4.60 gm), and later X, Ξ, and Σ issues (1/60=5.30 gm).
Note - the obverse legend should be IMP C C... the G being an engraver's error.
