Commentary of OGN numismatique on this coin: ''La seule localité dont nous pensons retrouver des lettres dans ce monogramme semble être Marsal. Cette proposition est d’Alain Poinsignon. Pourquoi n’y a t’il pas de lettre S. Très probablement pour éviter une confusion possible avec l’atelier de Marseille.''. Traduction: ''The only locality whose letters we expect to find in this monogram seems to be Marsal. This proposal is from Alain Poinsignon. Why there is no letter S. Most likely to avoid possible confusion with the Marseille mint''.
