Watch List notes:

China (People's Republic), gold 1/2 oz proof official Panda issue, 1989 Y, 2nd Hong Kong Coin Exposition, NGC PF 69 Ultra Cameo. KM-XMB43; PAN-113A. Only one higher at PF 70 in current NGC census. As Anthony points out, this medal "has no English inscription to identify it; not even an obvious date," causing some to misattribute it as simply GREAT WALL OF CHINA instead of Hong Kong. Mintage: 1,300 (planned; actual and surviving unknown). Pedigreed to the Gansu Collection of Chinese Panda Coinage.

Estimate: $900 - $1350
