| 裏面の説明 | The central vignette presents an intaglio view of the Bank of Sudan headquarters building in Khartoum, rendered in fine line engraving against a light guilloche background. Decorative floral and foliate border elements frame the design on all sides, with denomination numerals "50" at the upper corners and Arabic numeral equivalents at lower left. The issuer name and denomination appear in English above and below the building vignette respectively. |

The Bank of Sudan's P#31 series was issued during a period of acute fiscal strain — Sudan was running one of the heaviest debt-to-GDP burdens in Africa through the mid-1980s, and currency management was increasingly reactive rather than planned. Thomas De La Rue handled production throughout the series, a relationship Sudan had maintained since independence.
The 50 Piastres denomination circulated at the bottom of a system under pressure from inflation that would eventually force a complete redenomination in 1992. Notes from the later 1987 dates show heavier circulation wear as a rule, consistent with the denomination's heavy day-to-day use before smaller coinage became effectively worthless.
