2000 Francs

The BEAC's 2000-franc series introduced a revised signature matrix that produced three catalogued sub-varieties — 408Aa through 408Ac — distinguished solely by the rotating gubernatorial signatory paired against the fixed Aleka-Rybert countersignature. This kind of administrative turnover embedded in printed currency is unusually well-documented for the zone, and collectors working a type set often overlook that the three are technically distinct catalogue entries rather than variants of the same issue.

BEAC notes circulate across six member states simultaneously — Cameroon, CAR, Chad, Congo, Equatorial Guinea, and Gabon — with individual country codes differentiating intended distribution. The 408A series carries a country letter prefix that determines which of those territories the note was officially assigned to, a detail frequently lost once notes entered general cross-border use.
