1 Rial - Qaboos 25th National Day, Burj Al Nahda, Silver

Issued to mark the 25th National Day of Oman — commemorating Sultan Qaboos bin Said's accession following the July 1970 palace coup that deposed his father, Said bin Taimur. The elder sultan had ruled with extreme isolationism, banning sunglasses, radios, and foreign travel for ordinary Omanis; Qaboos's government used anniversary coinages throughout the 1970s–90s to project modernization abroad and consolidate legitimacy at home. The Burj Al Nahda, or Tower of Renaissance, takes its name directly from Qaboos's term for his development program — al-nahda, the awakening.
