1 Weißpfennig - William III

William III ruled Jülich-Berg through a long regency dispute and persistent dynastic pressure from neighboring Cleves, which made consolidated minting policy difficult. The Weißpfennig — literally "white penny," so called for the pale appearance of low-grade silver after washing — was the workhouse denomination of Rhenish commerce in this period, circulating alongside the heavier Albus issues in everyday market transactions.

The Noss and Schultze references place this firmly within a documented series, though survival rates for small silver from the lower Rhine in this decade are poor. Most examples that reach the market today show heavy wear consistent with extended circulation before abandonment.
