I2 Roman Republican Anonymous struck bronzes McCabe group I2, Uncertain, broad flans, complex deck structures, perhaps Apulia, 40 gram As.
This is an uncertain but likely official issue from Apulia, with possible stylistic links to RRC 85 H. Coins have broad flans, complex prow superstructures, and narrow prowstems. There are several different design varieties of the As, and the group includes an uncertain Triens and Quadrans.

Group I2 Illustrated coins, and selected other museum or published examples:
Given the internal lack of homogeneity in this issue, which is effectively a parking place for uncertain issues of Apulia, it is not useful to analyse weights, but from the five coins cited the weight standard appears to be about 40 grams.
As: 49.21 (RR, fig.I2.As.3*), 36.12g (Artemide 11E, fig.I2.As.2*), 38.31g (Artemide 34, fig.I2.As.1*). I am aware of one other example which is a die-match to fig.I2.As.2, and one other example with the design-style (but not die matched) to fig.I2.As.1. I have not seen any other example akin to fig.I2.As.1.
Triens: 12.05g, (BM.56.5.8, fig.I2.Tr.1)
Quadrans: 8.39g, (BM.56.5.12, fig.I2.Qd.1 )
