M1 Roman Republican Anonymous struck bronzes, McCabe group M1, RRC 339 and RRC 350B. Prow either right or left. Prow design includes Greek key decorative patterns with dots within, and waves under the keel. 12 gram As.
Prow is either right or left. Prow design usually includes Greek-key decorative patterns or matrix of squares with dots within, and waves under the keel. There may be a gated arrangement on deck, and sometimes there is an elevated peaked deck structure. The apotropaic eye, usual on all earlier issues, is either very small or not present. There is no central deck structure as was normal on all earlier issues. Designs which do not include the majority of these elements are likely to be imitations.
