Guinea-Bissau

Guinea-Bissau is the former Portuguese Guinea on the west coast of Africa.

In 1975-76, Cabral birthday and American Revolution sets again appeared in old Portuguese currency. The following issues would return to Pesos ("P").
 * Its first stamp was issued in September 1974 commemorating Amilcar Cabral. It was inscribed ESTADO DA GUINÉ-BISSAU.
 * In 1975, an old Portuguese Guinea WMO stamp was overprinted with a band of stars, also with REP. DA to the left of the inscribed "GUINE" and BISSAU to the right. Confusingly, it remained in old Portuguese centavos.
 * In 1997, inscriptions became REPUBLICA DA GUINÉ-BISSAU .
 * In mid-1983, inscriptions were changed again to just GUINÉ-BISSAU.
 * In 1984, inscriptions were sometimes changed back to REPUBLICA DA GUINÉ-BISSAU . By this time, year dates were being added to the bottom margins of stamps.
 * c.1986, old Portuguese Guinea snake stamps were surcharged with BISSAU added to the existing inscriptions.

 * Beginning in 1988, money was expressed a "5P00" for 5 pesos.
 * Beginning in 1990, currency was abbreviated as "PG".
 * In 1998, they gave up their own currency and switched to the CFA franc used by the former French colonies of West Africa, expressed as "FCFA".
 * Following a civil war in 1998-99, the country went into a period of great instability. Philatelically, this meant also that some of the usual suspects were printing bogus sheetlets and souvenir sheets marked "Guiné-Bissau". Apparently, today, Guinea-Bissau uses Stamperija Ltd. as their printers and postal agents. Quite interesting in that Stamperija has produced bogus issues for many countries. Here's their stocklist/catalog of official(?) Guinea-Bissau issues:
