50 Pounds L. 1985

The Bank of Sudan's 1985 issue came at a particularly unstable moment — the country was in the grip of severe economic deterioration and a balance of payments crisis that had been worsening since the late 1970s, with foreign debt spiraling and the Sudanese pound under sustained pressure. Higher denominations like this 50 Pound note were increasingly necessary for everyday transactions as purchasing power collapsed.

Thomas De La Rue printed this series, as they had most Sudanese issues going back to independence. The watermark remains the primary security feature — relatively modest for the denomination, reflecting the cost constraints Sudan faced in commissioning the series.
