BRUNEI. 1000 Dollars, 1978. London Mint. PCGS PROOF-69 Deep Cameo.KM-22; Fr-1. Commemorating the 10th anniversary of the Coronation of Sultan Hassanal Bolkiah. With a mintage of just 1,000 pieces, this impressive gold issue does not disappoint. With majestic surfaces that are completely mirrored, this piece offers a quality which is surely difficult to improve upon. Indeed, it is the finest graded example by PCGS, with an NGC PROOF-70 Ultra Cameo realizing a hammer of $19,000 (!) in January 2019.
