A1 Roman Republican Anonymous struck bronzes, McCabe group A1, RRC41 Large devices. Broad flans. Triangular box at keel with waves. 50-100 gram As.
The devices are large, and struck on broad flans. Obverses have large busts. The reverse prow usually has a triangular box at keel with waves within. The prow is separated from the left hand border, giving the impression of being a standalone object or statue. Otherwise, there are variable prow details: e.g. variable deck infrastructure, decorative dolphins, clubs, variable number of mariners(?) etc. The value mark on the As is under Janus’ head. Strikes are well centered.

Group A1 Illustrated coins, and selected other museum or published examples:
As: horizontal value mark: 51.70g (RR), 51.57g (RR, fig.A1.As.1*), 50.94g (RR); vertical value mark: 34.34g (Paris.A923, overstrike, fig.A1.As.2*), unique. Additionally d’Ailly cites two further coins with the horizontal value mark, a mediocre example of 33.32g in his own collection and a better one at 42.85g, from the Duc de Luynes collection, bequeathed to the BNF in 1862-63. Neither could be located in BNF Paris, 2011, and the latter does not appear in J. Babelon’s catalogue of the Duc de Luynes collection43.
