1 Pound

The Bank of Sudan's early pound issues were printed by De La Rue throughout this decade, but the changing watermarks — from rhinoceros to secretary bird — reflect deliberate administrative decisions rather than routine production updates. The rhinoceros watermark appeared only in the 1970 issue; by 1971 it had been replaced, and that substitution aligned with the broader reorganization of Sudan's central banking structure under Nimeiry's government following the 1969 coup.

The signature field is unusually informative here: three different signatories across ten years, with titles shifting between Governor and Chairman of the Board, tracking real institutional turbulence rather than ceremonial rotation.
