Banknote Billet Guinea-Bissau 50 pesos 1990

This 50 pesos banknote was issued by Guinea-Bissau on 1 March 1990. It belongs to series AB and represents a notable example of the country's monetary policy during that period, under the authority of the Banco Nacional da Guiné-Bissau.

The Guinean peso was the official currency of Guinea-Bissau since the country's independence in 1974, before being replaced by the CFA franc in 1997 when the country joined the West African Economic and Monetary Union (WAEMU). This 50 pesos banknote therefore belongs to a pivotal period in the monetary history of this small West African state.

Guinean banknotes of this era generally featured designs related to national identity, local fauna and flora, or historical figures linked to the independence struggle, most notably Amílcar Cabral, the founding father of the nation. The typography and graphic composition of these issues reflect the printing standards in use at the end of the 1980s, with security features adapted to the technologies of the time.

The issue date of 1 March 1990 is printed on the banknote, allowing precise identification of this issue within the national monetary production. The reference to series AB facilitates the classification and traceability of this banknote within numismatic collections and specialised catalogues.

Due to the short period of use of the Guinean peso and the country's relative economic isolation, banknotes from this series are of particular interest to collectors specialising in African currencies or in monetary issues with low print runs or limited circulation.
