拍品描述： China (Peoples Republic), silver proof 10 yuan (1 oz) Panda, 1987, NGC PF 69 Ultra Cameo. KM-167; PAN-58A. Whereas previous silver Pandas were in 0.900 silver, this year marks the first made in 0.999 fineness (hence exactly 1 troy ounce of silver). This issue also shows "excellent contrast between deep mirror fields and frosted devices" (Anthony). Currently only two are finer (at MS 69*) in the NGC census. Mintage: 31,000 (planned; actual and surviving unknown, but "much scarcer than that number [mintage] implies," according to Anthony). Pedigreed to the Gansu Collection of Chinese Panda Coinage.
