People's Republic gold Unicorn 500 Yuan (5oz) 1996 PR69 Ultra Cameo NGC, KM949. Serial #10 (from a tiny mintage of only 108 pieces) stamped in the edge by the mint. Housed in an NGC "Jumbo" holder. An unimprovable example of this incredible gold rarity. The pristine fields are deeply mirrored, and the devices heavily frosted, yielding superb cameo contrast. The strike is bold and the surfaces flawless. None have been certified finer.
Estimate: 35000-40000 USD
