1 Ducat - Antonio Venier

The Genoese Mahona — a consortium of merchant families who purchased administration of Chios from Genoa in 1347 — struck ducats deliberately imitating the Venetian zecchino in weight and fineness to ease trade across the Aegean. Venier's name appears on this issue despite him being Doge of Venice, not a ruler of Chios; the practice was to borrow Venetian ducal nomenclature as a mark of monetary credibility rather than political authority.

The island's mastic monopoly funded this coinage. Chios controlled the only productive groves of Pistacia lentiscus in the medieval world, and that single commodity made the lordship wealthy enough to sustain a gold issue through most of the fourteenth century.
