I'd also be open to a trade for the MS70 2001D G500Y. The following coins come to mind as interesting:
1988 Gold China Medal New Orleans International Investors Conference PF69
1989LD G50Y MS69
1990SD G50Y MS69
1991P China G50Y PF69
1992P China G25Y NGC PF69
1992P China G50Y PF69
1994P China G50Y PF69
1995 LD China G25Y MS69
1997 China G100Y Penguin PF69
1998 China G50Y Panda MS69
1999 China G10Y Panda Large Date Serif 1 MS69
2000 China G50Y Panda Mirror MS69
2001D China G200Y Panda MS69
If you have a few of these or some other better-date gold 1/2 or 1/4 oz pandas, PM me and let's see if we could come up with a trade. I have a number of other coins I could throw into the mix to round out a trade. I'd be looking to ship the coins within the US. Thanks.
