1 Rijksdaalder `Helmeted Rijksdaalder / Prinsendaalder` Horn

West Friesland began striking its own daalders almost immediately after the northern provinces broke from Spanish rule, and the Horn mint was one of the most active early producers. This 1584 piece falls squarely in the opening years of the Dutch Revolt, when minting rights were exercised aggressively by provincial authorities to fund an ongoing war with no end yet in sight. The Prinsendaalder designation reflects its association with the Orangist cause — William of Orange was assassinated that very year, on July 10, 1584, in Delft.

HPM Wf 11 is among the earlier documented die marriages for this provincial type.
