K1 Roman Republican Anonymous struck bronzes McCabe group K1, Related RRC 183 wolf and twins, RRC 184 butterfly and vine-branch. Small dumpy flans, thick denomination mark, wide curving prowstems. 25 gram As.
These coins are related to one style of RRC 183 wolf and twins or RRC 184 butterfly and vine-branch, having small dumpy flans, prominent forehead hair, abnormally thick denomination marks, and wide, curving and converging prowstems. Note that there also exists another RRC 183, RRC 184 style which is struck on broad thin flans with finer die engraving, suggesting that two workshops existed at the time.
