The latest sale of this wine in Hong Kong in May 2010, held by Sotheby's, saw new world records being set for this extraordinary wine:

28 | 556,600 (71,323 USD) | 200,000 - 340,000 | Asian Private | Château Cheval Blanc 1947 (3 bts)
***WORLD RECORD AT AUCTION [e.g. $23,774/bottle].

29 | 387,200 (49,616 USD) | 120,000 - 200,000 | Asian Private | Château Cheval Blanc 1947 (1 mag)
***WORLD RECORD AT AUCTION

On June 17, 2009 Sotheby's (London) sold various lots of this wine as single bottles.
Lots 100 & 101 | £9,430 ($15,532) | 75cl
Lots 102 & 103 | £9,200 ($15,153) | 75cl
Lot 104 | £18,400 ($30,307) | 1.5l
Interestingly, Christie's New York sold a lot of 3 magnums a few months later for $60,000 which seems like good value albeit it may not have had the provenance. 2 magnums (not Chateau bottled) sold two months later in Hong Kong for almost $25,000, and in December, 2009 two magnums sold at Christie's in New York for $31,200.
