1/4 Rial

Oman's switch from the Gulf Rupee to the Rial Saidi in 1970, and then the rebranding to the Rial Omani in 1972 following Sultan Qaboos's consolidation of power, left the Central Bank issuing successive series in quick succession throughout the decade. This 1977 note belongs to the first series issued under the Central Bank proper, which had only been formally established in 1974 — replacing the Oman Currency Board that had handled the transition years.

Bradbury Wilkinson printed Omani notes through this entire formative period. The quarter-rial denomination was a practical necessity given the rial's high purchasing power at the time.
