20 Pounds

Sudan's 1991 note issue came during a period of acute economic strain following the 1989 coup that brought Omar al-Bashir to power. The new military government inherited accelerating inflation and a currency already under severe pressure from years of civil war financing — the 20 Pounds denomination was meaningful in 1991 but would be eroded quickly by the hyperinflationary spiral that followed.

Thomas De La Rue's involvement is worth noting: the relationship between Khartoum and London-based printers grew increasingly complicated through the 1990s as Sudan faced international sanctions. This may be among the last series De La Rue produced for the Bank of Sudan before that relationship lapsed.
