OLD BOTTLES OF WINE FOR SALE

[Bflores]

Hello:
I am the happy owner of a 1949 Richebourg Red Burgundy wine bottle, yes 1949, from France, in excellent condition, I would like to find out where can I sell it, I bought from a friend that needed cash about ten years ago, and now I would like to see my profits, can you tell me how much can it cost in these days?? and where could I sell it??
I also have a bottle of Chateau Laffitte Rottschild 1975, from Phillipe laffite, for sale to tjhe best bidder,it has a number but I would have to retieve it from the bottle. Thanks
