The Venetian Ducat was a gold coin used in the Republic of Venice from the 13th century until the 18th century. It was widely recognized for its high purity and weight, making it a trusted currency in trade across Europe and the Mediterranean. The coin typically featured the image of Saint Mark, the patron saint of Venice, on one side, and the Doge of Venice on the other. The ducat became a standard for other currencies and influenced the design of coins in various regions. Its significance extended beyond Venice, as it was used in international trade and became a symbol of the city's economic power during the Renaissance.
