I can't believe it was late last year that this thread was begun by newtraffic2, and 8 months ago left unfinished

The history of the grosso in southern Italy was left hanging, and as luck would have it, I've been working on the Sicily/Naples sections of Numista recently.
To recap ...
The Norman king Roger II struck a large silver coin (2.5 grams) called a ducalis based on Byzantne designs around 1140 (post of 12/25/2025). In several senses, it could be considered as a sort of prototype for the Venetian grosso which followed it about 40 years later (covered at the beginning of the thread).
The next major development, in 1279 was striking of the first Italian coin to (nearly) match the French gros tournois in size and silver content, the carlino of Charles I of Anjou, called a saluto d'argento (post of 12/23/2025).
In 1303, his son, Charles II replaced the first carlino type with a new design, featuring the enthroned king obverse, and a cross decorated with fleur-de-lis reverse (MIR 24, N#& 71471):
