UNLISTED FOR RULER. RIC lists this issue only for Constantine (p. 595).
General note from p. 576: "This very small issue - the coins are all extremely rare - comprises only Herculi Victori, for Constantine, and Iovi Conservatori and Soli (sic!) Invicto for Maximinus. Emissions for Licinius are not recorded. The highest officina number recorded is Z. Date, 313".
Footnote 1 on p. 595 emphasizes that "Evidence for this isue is very poor, and the full number of officinae is uncertain". All coins listed in RIC are cited after Voetter and Sutherland probably have not seen them.
Coin should be listed before CYZICUS 108.
