I think it very unlikely that this is the "C" die letter variety. Not only is there very little evidence in the right area to the left and below the lighthouse, but also I am pretty sure this is reverse G, whereas all the "C" die letter examples so far found are reverse F.
To be an F reverse the hair at Britannia's nape would extend much further - almost to the shoulder drape, and the underside of the outstretched arm would be slightly curved.
