No, I can't summarize that. The confusion may come from the usual denominations we give to them in France, the big "chunk" being called double maiorina and the mid one just maiorina. As for the "seventh phase" the reference is in P.Bastien "le monnayage de Magnence" # 135 (15 ex), 7ème phase du monnayage de l'atelier entre début 353 et le 10 août 353 - RIC.34 (C) Hope it helps Q
