Watch List notes:

China (People's Republic), platinum proof 100 yuan (1 oz) Panda, 1990, NGC PF 68 Ultra Cameo. KM-280; PAN-129A. The final date of a four-year set in platinum, in fact "the key to this short series" (Anthony), due to technical problems in minting, but also due to meltage in the 1990s.

Estimate: $1800 - $2600
