that's a cool new coin aleg! and good info/maps as well! i just don't have much to share here...this common social war era coins is the best i can muster...
So your coin is 105 and what Campana considered a Series 7a (mine is 7b) and has 2 die combinations. There were 18 examples known to Campana in his book which, from what I can tell, sort of puts your coin in the middle as far as rarity in the series. Keep in mind, pretty much all Bellum Sociale are scarce to rare. Yours appears to be more rare than mine. The book is in Italian which means I pretty much look at the pictures and tables since I can't really read it. Given the weight, I don't think yours is one known to Campana unless it is one of the examples that doesn't have a weight on it. I checked (m) which is Haeberlin as you're sort of close but that's not your coin. I don't have either of the unknown weight catalogues unfortunately so I can't check them.
