Grosso Agontano

The agontano takes its name from Ancona, whose grosso became the dominant trade silver of the central Adriatic from the mid-thirteenth century onward — imitated so widely across the Marche that municipalities like Ascoli Piceno struck their own versions to avoid dependence on a rival city's coinage. Ascoli's commune gained minting rights during the fragmented signorial period when imperial authority over the region had effectively collapsed, leaving individual cities to negotiate monetary privilege directly with local power brokers.

CNI XIII places this among a small, poorly-differentiated group, reflecting how little the Ascoli series has been studied relative to Ancona's own issues.
