25 Centimes P.O.W. Cage

Prisoner of war camp canteen scrip occupies one of the more unglamorous corners of military notaphily, but it served a real administrative function: preventing captured soldiers from accumulating currency that could fund escape attempts. This 25 centimes piece was almost certainly issued in a French or Belgian theater camp — the centime denomination points firmly to francophone accounting, not British or German camp systems, which used their own internal units.

The Cambridge reference is the primary authority here; documentation on individual cage canteens is sparse, and issuing unit records were rarely preserved after armistice.
