1 Daalder 'Arendsrijksdaalder'

The Arendsrijksdaalder — "eagle rijksdaalder" — was struck by Friesland during the opening years of the Dutch Revolt, when the northern provinces were asserting independent monetary authority while simultaneously fighting for survival against Spanish forces. Friesland's mint at Leeuwarden produced these on the authority of the provincial States rather than any sovereign, a deliberate political act at a moment when the question of who governed the Netherlands was still very much unresolved.

The type falls within a broader family of German-influenced daalder coinage circulating through the Low Countries in this period, but Friesland's provincial issues are meaningfully scarcer than those of Holland or Zeeland. HPM Fr28 covers a span of six years precisely because attribution to a single year within the series is rarely possible from the coins themselves.
