This isn’t an actual argument yet. It’s an instinct. I agree that this is the half value coin (Sambon 146) which goes with the full value coin (Sambon 145) with an elephant on it (see Baglione 1976).
I think that the obverse is more likely to be a Celtic warrior wearing an animal skin (bear probably) and that some how this is supposed to correlate with the dog. I’ve a hunch based on the appearance of these coins in regional Italic museums that we should date the series to late 218 early 217 while Hannibal is his winter camp having conquered the Taurini and working on improving his troop moral and recruiting Italic allies before going to meet the Roman arm near Arretium (Polybius 3.60 onwards).
The problem is I can’t find the text references or images to back my thinking up at least not to my own tastes and I need to move on to other things.
