100 Francs

The Banque Centrale de la République de Guinée's 100 Francs is a low-denomination note that survived in active circulation far longer than its condition typically suggests — Guinea's humid equatorial climate accelerates paper degradation significantly, and heavily soiled, limp examples are the norm rather than the exception for this series. The 1998 start date places initial issue during Lansana Conté's presidency, a period of chronic monetary instability driven largely by reliance on bauxite revenues and persistent fiscal deficits.

The extended print run through 2012 reflects sustained demand at the street level, where this denomination still bought goods in a country where the parallel exchange rate often diverged sharply from official figures.
