The sheer number of signature combinations on this single Pick number — sixteen distinct pairings across two decades — reflects the political volatility of the eight-member WAEMU zone rather than any change in the note's design or printing. The BCEAO's dual-signature requirement, pairing a national committee president with the governor, means that every ministerial reshuffle or gubernatorial appointment in any member state can generate a new collectible variety without a single change to the plate.

Oberthur's Chantepie facility has held the BCEAO printing contract for this denomination throughout the series run. The security specification remained largely static after 2003 — no upgrade to holographic strip or color-shifting ink was applied, which collectors of the later dates sometimes note as a limitation given the note's high face value.
