1 Ducat

West Friesland ducats of this type were struck under the authority of the States of Holland and West Friesland, one of the seven sovereign provinces of the Dutch Republic, during a period when the Netherlands was simultaneously fighting the Eighty Years' War against Spain and funding the most aggressive commercial expansion in European history. The ducat served as a hard-currency instrument for VOC and WIC trade settlements, circulating far beyond Dutch borders into Baltic grain markets, Levantine ports, and the nascent Atlantic trading networks.

The remarkably long uninterrupted type-span — nearly seven decades without design revision — reflects deliberate monetary conservatism. Foreign merchants trusted the coin precisely because it didn't change.
