| Comments |
The Bank of Sudan's engagement with Thomas De La Rue for this series reflected a pattern common among newly consolidated African central banks of the period — outsourcing high-denomination production to established European security printers while domestic infrastructure remained limited. Sudan was simultaneously managing the economic strain of absorbing refugees from the Chad conflict and the early pressures of southern insurgency, both of which were quietly destabilizing the pound well before the note's withdrawal.
The watermark is the sole mechanical security feature — no security thread, no fluorescent inks. Relatively straightforward specification for De La Rue at this production date, suggesting cost constraints informed the brief.
