I1 Roman Republican Anonymous struck bronzes McCabe group L2, RRC56 Uncertain, broad smiling head, prominent beard, short rounded prowstem. Small thick flans. 35 gram As.
This is an uncertain issue on small thick flans with broad smiling heads and prominent beards. There are similarities to RRC 86B anchor and Q including flan size, style of Janus head, a prow with rounded prowstem, and top two keel lines which join mid-prow. There are also some similarities with Rome group G1 and with Etruria group E1. The engraving is of high quality, and the flan production and strikes are more typical of Etruria than Apulia. So the mint location is uncertain.
