Only 1 Graded Higher, and 1 of 35 graded in this state!

I purchased this coin for a steal and just received it, it's so much more amazing then in the picture! It is a New York Expo 1989 Panda/horse, This coin is 1 of 4000 that were minted! There is only 35 graded in pf69 and only 1 Graded higher in pf70, This coin is simply a beauty of rarity that words really cannot describe!

All in all there is only 45 coins of the 4000 graded to date, the only problem is with the 10Y China commems start in 1991 and this coin is a 1989 so I cannot find a spot to add this in, I tried every 10Y china spot but cannot add it anywhere! I would assume that this coin would be an amazing registry coin that would be worth some great points? I'm hoping that Someone at NGC can help me or edit the 10Y Commem Registry set that has all the other 1oz expo panda coins to have the 1989 NYC expo coin so I can add it my registry or tell me what registry set contains this coin so I can add it?

Here is a Picture of the coin, its a beauty and I hope you all enjoy it as much as I do since I cannot stop looking over this coin trying to find the flaw to why it was graded a PF69 and not a PF70 cause Really I cannot find a reason why!
