The Museum Correr Library of Venice collects among its important manuscripts some epistolary collections that allow to shed light on the numismatic interests of two important members of the Gradenigo family, who, although distinguished by different life choices, were united by the common passion for coins collecting. They are Giannagostino Gradenigo (1725-1774), bishop of Chioggia and, then, of Ceneda, and his brother Jacopo (1721-1796) who pursued a military and political career.
