H1 Roman Republican Anonymous struck bronzes McCabe group H1, RRC56 Half-weight fractions, overstrikes on Punic bronzes. Styles derivative from various issues of groups G. 15-20 gram As.
These coins are overstrikes on Punic and other captured bronzes, at half usual the weight, and can be clearly separated by weight, as well as by design, from Rome group G issues. These are possibly from Sardinian, Sicilian or non-Roman Italian mints. Design is based on prototypes of Rome mint coins of groups G1, G3, and G4, but with simplified prow designs; thus group H post-dates group G. Engraving is of good style, with large heads relative to flans.
