Rijksdaalder `Arendsrijksdaalder` Piedfort at double weight

Utrecht's piedfort production in the 1580s falls squarely within the chaos of the early Dutch Revolt, when provincial mints operated with considerable autonomy and occasionally struck double-weight pieces for presentation or approval purposes — likely submitted to the States-General as die trials or gifted to civic dignitaries. The Arendsrijksdaalder type itself was short-lived; the rijksdaalder would soon be standardized across the Republic's mints under pressure for monetary uniformity, making these thicker provincial variants a footnote to a coinage system still actively inventing itself.

The Delmonte S#817a designation signals extreme rarity within an already thin series.
