1 Grosso

Acqui Terme, ancient Aquae Statiellae, was a bishop's city whose mint operated under persistent jurisdictional friction between episcopal and communal authority. This grosso falls within the period when northern Italian communes were aggressively asserting minting rights, often in direct defiance of imperial grants held by their bishops. The precise dating range reflects genuine uncertainty — no documentary record pins the commune's first independent silver issues to a specific year.

The MEC XII attribution places it firmly within the broader Ligurian-Piedmontese monetary sphere of the mid-thirteenth century.
