The BCEAO's signature rotation on this series is unusually dense — more than a dozen combinations across two decades, reflecting the mechanics of a monetary union where the national Minister of Finance countersigns alongside the central bank Governor. Each member state holds the minister's seat in rotation, meaning signature changes track political and administrative turnover across eight countries simultaneously. A collector building a complete run by signature pair faces a genuinely demanding task.

The "T" suffix in the Pick reference designates the BCEAO's Togo-specific issue. Functionally identical to parallel printings for other member states, differentiated primarily by the national letter code embedded in the serial number prefix.
