50 Francs Brussels World's Fair 1935, French text

Belgium issued this coin specifically to commemorate the 1935 Brussels Universal Exposition, one of the largest world's fairs of the interwar period, which attracted over 20 million visitors despite the grinding economic pressures of the Depression. The exposition was built on the Laeken plateau and deliberately showcased Belgian industrial and colonial ambition at a moment when both were under strain.

The reduced silver fineness — well below Belgium's earlier coinage standards — reflects treasury constraints of the period. A parallel issue with Dutch (Flemish) text was struck simultaneously, the bilingual split a legal requirement under Belgium's linguistic parity laws codified in 1932.
