Watch List notes:

China (People's Republic), platinum proof 100 yuan (1 oz) Panda, 1987 S, NGC PF 69 Ultra Cameo. KM-A163; PAN-51A. With S mintmark for Shanghai. Only one better (MS 70) at NGC. First of a four-year set of platinum 100 yuan that Anthony calls "both a challenge and a joy to assemble." This date in particular Anthony calls: "a scarce coin but... rarer than the mintage suggests. During the mid-1990s there were times that the platinum content of this coin overshadowed its numismatic worth." Mintage: 2,000 (planned; actual and surviving unknown). Pedigreed to the Gansu Collection of Chinese Panda Coinage.

Estimate: $2000 - $3000
