50 Centimes Société Anonyme Token Coinage

The Société Anonyme de la Grande Comore was a French colonial plantation company operating on Grande Comore island, and like similar enterprises across French colonial Africa, it issued its own token coinage for use within its labor system — paying workers in scrip redeemable only at company stores, effectively tying wages to the issuing company itself. The 1915 date places this squarely in the wartime period when metropolitan France was diverting metal and administrative attention to the Western Front, leaving peripheral colonial operations to manage their own exchange needs.

Aluminium was the practical choice given wartime metal shortages.
