拍品描述： China (Peoples Republic), platinum proof 50 yuan (1/2 oz) Panda, 1990, NGC PF 69 Ultra Cameo. KM-279; PAN-132A. Unique design, as is the case for the smaller platinum Panda coins for this year; but unlike the lower denominations, the entire mintage of 50 yuan (the only 1/2 oz platinum Panda from the China Mint) was put into three-coin denomination sets, and therefore it is scarce individually, especially considering meltage in the 1990s. Mintage: 2,500 (planned; actual and surviving unknown but certainly much less). Pedigreed to the Gansu Collection of Chinese Panda Coinage.
