1 Rial - Qaboos Nakhl Fort

Issued to mark Oman's 25th National Day, this coin commemorates the Silver Jubilee of Sultan Qaboos bin Said's rule following his 1970 coup against his father, Said bin Taimur. The elder Sultan had kept Oman in deliberate isolation — no schools, no hospitals, no paved roads — making the modernization Qaboos oversaw in the intervening quarter-century genuinely dramatic by any regional comparison.

Nakhl Fort, a pre-Islamic structure rebuilt extensively during the Ya'aruba Imamate period of the 17th century, sits at the base of the Al Hajar mountains in the Batinah region.
