A2 Roman Republican Anonymous struck bronzes, McCabe group A2, RRC41 Large devices, broad thin flans, three parallel lines at keel, no waves. 65 gram As.
The devices are large, and struck on broad thin flans. Types are generally low-relief. Obverses have large busts. The reverse prow usually has three almost parallel lines at keel, with no waves between the lines. The prow has the standard design of all later bronzes, and never has any decorative additions. The prow design merges with the left hand border of the coin. The value mark on the As is over Janus’ head. Sometimes there are weak strikes or casting holes on Triens, Semis and As. Some coins are overstrikes on Roman semilibral or foreign coins.
