The Agontano was the currency used by the Italian Maritime Republic of Ancona from the 12th to the 16th centuries during its golden age.
It was a large silver coin of 18-22mm in diameter and a weight of 2.04-2.42 grams, of roughly equivalent value to the Milanese Soldo.
[2] The coin, also called "Grosso Agontano", was a great success and its type was imitated in other cities of Marche and also in Emilia-Romagna, Tuscany, Lazio and Abruzzo.
[6] On the obverse the Agontano displays a cross enclosed by a circle around which is the inscription DE ANCONA.
The saint's head, with the halo, interrupts the circle that encloses the rest of the body.
