1 Ducat - John of Campofregoso

Chios was leased to the Genoese Maona — a private colonial consortium — from 1347 onward, making its coinage the product of merchant capital rather than sovereign authority. John of Campofregoso held the Dogeship of Genoa twice, the second time from 1447 to 1448, which tightly brackets this issue to a single turbulent year. The ducat type was struck explicitly to facilitate trade with Venetian-dominated markets, mimicking Venetian weight standards to pass at par in eastern Mediterranean commerce.

The Lunardi S22 classification places this among documented Chiot imitative issues — coins designed from the outset to circulate as proxies for Venetian ducats without being forgeries in the modern legal sense.
