Watch List notes:

China (People's Republic), platinum proof 10 yuan (1/10 oz) Panda, 1990, NGC PF 69 Ultra Cameo. KM-277; PAN-135A. This issue marks the first platinum 10 Yuan in the series, with its own unique design (as opposed to later years in which the design is the same as for the gold). Only seven higher at PF 70 in the current NGC census. Mintage: 4,500 (planned; actual and surviving unknown but certainly much less due to meltage in the 1990s). Pedigreed to the Gansu Collection of Chinese Panda Coinage.

Estimate: $300 - $450
