500 Francs CFA South Korea Bottle Cap

Chad's CFA franc is issued under the authority of the Bank of Central African States, which means a landlocked Sahelian nation had to formally coordinate with a six-country monetary union to produce a coin celebrating South Korean soju culture. That bureaucratic incongruity is part of why these novelty issues exist at all — the BEAC licenses small commemorative runs to generate hard currency revenue entirely detached from domestic monetary circulation.

The bottle cap shape is achieved through a scalloped die strike, not a separate fabrication process.
