1 Denier Tournois - Nicolas I

Nicolas I Sanudo ruled the Duchy of the Archipelago as a Venetian vassal, and his deniers tournois are direct imitations of the French denier tournois — a denomination that spread across Latin Greece following the Fourth Crusade as Frankish coinage became the commercial lingua franca of the Aegean. The Schlumberger reference places these firmly within the broader corpus of Crusader imitative coinage, a category where attribution remains contentious and die-link studies have repeatedly revised earlier assignments.

Nicolas I died without legitimate heirs, ending the Sanudo dynasty after over a century and a half of control over the island duchy.
