1 Rijksdaalder piedfort of quadruple weight

Piedforts of this weight — four times the standard Rijksdaalder flan — were never produced for circulation. The Mint of West Friesland struck these almost certainly as presentation pieces, likely for gift exchange among civic officials or foreign dignitaries, a practice deeply embedded in Dutch Republic diplomatic culture by the mid-seventeenth century. West Friesland was among the more independent-minded of the provincial mints, frequently producing off-metal and overweight specials that deviated from the Union of Utrecht's monetary conventions with apparent impunity.

The Delmonte S#940b attribution places this firmly within the specialist piedfort literature rather than general coinage catalogues — unsurprising given that surviving examples are counted in single digits.
