1 Denier Tornese - Battista Giustiniani di Campis

Battista Giustiniani di Campis held the podestà of Chios for a single year under the Maona — the Genoese syndicate that administered the island from 1347 until the Ottoman conquest of 1566. The Maona's constituent families rotated administrative authority annually, which is why so many Chiot issues are tied to a single magistrate's brief tenure, making per-administrator types genuinely scarce rather than artificially so.

The tornese denomination itself derives from the French denier tournois, introduced to the eastern Mediterranean through Crusader coinage and retained by successive Genoese administrators long after it had ceased circulation in the west.
