500 Francs CFA Thai Bottle Cap

Chad's CFA franc is issued through the Bank of Central African States, but this piece has nothing to do with monetary policy — it belongs to the collector novelty category that the Paris-based minting contractors have aggressively expanded across francophone African issuing authorities since roughly 2015. The Thai bottle cap motif references the Chang beer brand, whose distinctive bottle caps have become minor collector objects in their own right across Southeast Asia.
