1000 Francs Jeux Olympiques Mexico 1968

Chad issued a wave of commemorative silver pieces in the early 2000s under licensing arrangements that had little to do with the events depicted — this 1968 Mexico Olympics piece appeared 35 years after the games themselves closed. The issuing authority was essentially the Banque des États de l'Afrique Centrale, though the coins were produced for the collector market and never meaningfully circulated in N'Djamena or anywhere else.

The 1968 Mexico City Games were the first Olympics held at high altitude, which measurably affected performance across endurance events and inflated results in explosive disciplines.
