Sultan Hassanal Bolkiah I gold Proof "10th Coronation Anniversary" 1000 Dollars 1978 PR70 Ultra Cameo NGC, KM22, Fr-1. Mintage: 1,000. An entrancing and entirely immaculate offering that easily warrants its Ultra Cameo designation by its heavily mirrored surfaces and thick device frosting, producing a day-and-night contrast. One of only 6 specimens at NGC to presently have received technical perfection, we note that the last such example we offered brought $22,800 in our January 2019 NYINC sale 3071 (lot 30165).
