Daalder - Margaret IV van Brederode with titles of Ferdinand

The Abbey of Thorn was one of the so-called "free imperial abbeys" of the Low Countries — a secular canoness chapter whose abbess held the rank of imperial princess and exercised genuine territorial authority, including the right to strike coin. Margaret IV van Brederode held that position from 1543 until her death in 1577, and this daalder was issued under her authority but carrying the titles of the Habsburg emperor Ferdinand I, a political formality that acknowledged overlordship without surrendering the mint privilege itself.

The 1560–1561 dating places production squarely in the period when the daalder was consolidating as the dominant large silver denomination across the Habsburg Netherlands, driven partly by the 1558 imperial monetary ordinance.
