MUSCAT AND OMAN. 1/4 Anna, AH 1315 (1897). Heaton Mint. Faisal bin Turki. PCGS MS-64 Brown.KM-3.1. This exceptionally fetching issue in bronze renders a lovely and enticing twirl of luster beneath the satiny finish. Some mint red hugs the legends and devices, and just the faintest touch of chattering in the fields renders this piece as fully engaging.
