These coins were struck at the outset of Jaafar Nimeiry's regime, which had seized power in the May 1969 coup. The Bank of Sudan — established only in 1960 to replace the Sudan Currency Board — issued this series as the country was still consolidating its post-colonial monetary infrastructure. Nimeiry's government would go on to dramatically remake Sudanese currency in 1992 with the introduction of the new dinar, but the early 1970s issues circulated through a period of relative political consolidation before the prolonged civil war made ordinary commerce in much of the country deeply unstable.
