price on Chateau Latour 1949

[jeffced]

I would like to know the approximate value of the following wine:
Grand Vin De Chateau Latour-Premier Grand Cru Classe-Pauillac-Medoc 1949.
I want to donate this wine to a fundraiser/auction and I would like to have a minimum value to set the opening bid.
Thank you'
jeff

In my Wine Spectators Ultimate Guide to buying Wine, it says the average price your wine goes for in auctions is $620. It also says it will likely hold for at least another decade. It's points were 94.
