K3 Roman Republican Anonymous struck bronzes McCabe group K3, RRC 197-198B/1b and fractions. Peaked deck structure, value before prow, unkempt beard, bulbous prowstem. 25 gram As.
This issue includes RRC 197-198B/1b and its related fractions. There is always a peaked deck structure, and the value mark is before the prow on all denominations (note that all peaked deck structure Asses, with a value mark above the prow, are from one of the earlier groups C2, C3 or J2). The obverse style, with an unkempt Janus beard, the reverse prow style, and the bulbous prowstem are as per RRC 196 star. The peaked deck structure and denomination positions are as RRC 194 anchor. There is a homogeneous style, suggesting a single engraver.
