Watch List notes:

China (People's Republic), gold 1 oz proof official Panda issue, 1988, Basel International Coin Week, "1 oz Pt" error, 1988, NGC PF 68 Ultra Cameo. KMX-MB21; PAN-90A. When browsing the NGC census for this error issue, one must search under PANDA SERIES as opposed to MEDALS per the previous lot, which is the same issue but struck with a proper gold die and not the platinum die ("Pt") as we see here. Mintage: 600 (estimated), but supposedly only 298 pieces were put into circulation. Pedigreed to the Gansu Collection of Chinese Panda Coinage.

Estimate: $1800 - $2600
