Watch List notes:

China (People's Republic), brass 32mm proof official Panda issue, 1988, Hong Kong Coin Exposition, NGC PF 69 Ultra Cameo ("top pop"). KM-unl; PAN-94A. As mentioned by Anthony, this brass issue was only given out to 100 or so dealers with tables at the show, so it may actually be the lowest-minted of the 1988 "show medals" series (here reverted to OFFICIAL PANDA ISSUE by NGC, none at higher grade). While the panda side is the same, the reverse of this issue is quite different from the gold. Mintage:
