CN. POMPEY MAGNUS (Pompey the Great). 43-36 BC. Æ As (23.53 gm). Sicilian mint. 

Laureate head of Janus with the features of Cn. Pompeius Magnus; 
MAGN above 
Prow of galley right; PIVS above, IMP below. Crawford 479/1; 
Sear, CRI 336; Sydenham 1044a; RPC I 671; BMCRR (Spain) 101-102. EF, 
exceptional green patina and perfectly centered.

This type is traditionally assigned to Spain during the period 
45-44 BC, but the issue is more likely to have been struck in 
Sicily after Sextus Pompey's arrival in 43 BC; the edges are 
rounded unlike the straight edges of the Spainish pieces 
and the style of this issue varies considerably suggesting that 
there may have been several mints involved in its production. 
Regardless of when and where it was struck, it is from the final 
issue of the Janus/Prow Republican bronzes.
