25 Centimes Willebroeck

Belgian municipal emergency notes issued during the German occupation of World War One fall under the broad category of "guerre" or siege currency — local authorities, stripped of normal banking access, printed their own small-denomination scrip to keep commerce moving. Willebroek, an industrial town on the Brussels-Scheldt canal, was no exception. These communal notes were technically obligations of the issuing municipality, redeemable in theory but often left unredeemed after the armistice when many communes quietly let the liability lapse.

Small-format paper issues from Flemish communes of this period are disproportionately fragile — thin stock, heavy handling, and damp storage conditions mean intact survivors are less common than their original print runs would suggest.
