1/4 Daalder 'Batseler / Sprenger' - In the name of Ferdinand I

The Abbey of Thorn was one of the more unusual monetary authorities in the Low Countries — a free imperial abbey whose abbesses held the rank of imperial princess and exercised full secular lordship, including the right to strike coin. This quarter daalder was issued under that privilege during the reign of Ferdinand I, Holy Roman Emperor, whose name the abbey invoked as the legitimizing authority on the coinage despite operating with considerable autonomous latitude.

The names Batseler and Sprenger in the catalog designation refer to the mint masters active at Thorn during this period — a useful anchor for die study given the abbey's small and irregular output.
