500 Francs Belges / Belgische Frank

The Belgian Army's occupation currency series was produced to pay troops stationed in Germany following the Allied victory, operating outside the civilian banking system and not redeemable through ordinary commercial channels. These military francs circulated in a tightly controlled environment — shops, canteens, and authorized outlets within the Belgian occupation zone around Liège and later the Rhine sector — which kept them largely out of civilian hands and off the black market, at least in theory.

Survivor rates are uneven across the series. The 500-franc denomination saw lower per-unit print runs than the smaller values, and post-demobilization redemption was strictly enforced, with unredeemed notes ordered destroyed by 1948.
