Watch List notes:

China (People's Republic), gold proof piefort 50 yuan (1 oz) Panda, 1991, 10th Anniversary of the Issuance of Chinese Panda Commemorative Coins, NGC PF 69 Ultra Cameo ("top pop"). KM-357; PAN-158A. One of only two double-thickness issues in the entire Panda series (the other being the next lot in silver), both struck this year to commemorate the 10th anniversary of Panda coinage. Anthony: The piefort 50 Yuan "stands out as the sole 1 oz. gold Panda with less than 100 Yuan in face value" and "commands a price several times higher than its intrinsic gold value." None in PF 70 in the current NGC census. Mintage: 2,500 (planned; actual and surviving unknown). Pedigreed to the Gansu Collection of Chinese Panda Coinage.

Estimate: $3000 - $4500
