500 Francs

The Banque des États de l'Afrique Centrale — known by its French acronym BEAC — serves six member states simultaneously, which means the same base note design circulates across Cameroon, Central African Republic, Chad, Republic of Congo, Equatorial Guinea, and Gabon, differentiated only by a letter code and country designation. Chad's issues carry the letter "C" and the République du Tchad overprint. Four signature combinations across this series reflect the high turnover in BEAC governorship and national directorship during the late 1980s, a period of severe fiscal stress in the franc zone compounded by the collapse of commodity export revenues.
