1/2 Daalder Pewter, Klippe, Zierikzee mark

Zierikzee fell under Spanish siege in 1575–76, and like several Dutch towns during the early phases of the Revolt, the besieged civic authority struck emergency coinage to pay troops and maintain commerce when regular money became impossible to obtain. These klippe — square-cut planchets — were a deliberate expedient, not an aesthetic choice. Pewter was used because silver wasn't available in sufficient quantity, making these pieces among the most materially humble emergency issues of the entire Dutch Revolt.

The Zierikzee siege obsidional series is exceptionally rare in any grade; pewter corrodes aggressively, and most survivors show significant surface degradation.
