Oman
Qabus bin Sa'id gold Proof 1/2 Omani Rial AH 1397(1976) PR69 Ultra Cameo NGC, KM58. Mintage: 1,000. An essentially flawless example that features the image of Fort Mirbat (incorrectly noted on holder) fully draped in satin, and set atop jet-black pools of reflectivity. Scarce so fine and with a limited mintage of just 1,000 pieces.
