wine prices

[CrystalAdams]

I was looking for some prices on the following bottles of wine, and whether or not they are still drinkable.

Liebfraumilch Glockenspiel
Rheinpfalz (Light White Thine Wine)
1971

Barton & Guestier
Chateauneuf-Du-Pape
1971

Saint-Emilion
Appellation Controlee
Bottled and Shipped by:
Dourthe Freres
Imported by The House Of Burgundy
New York, NY
1969
It also says that this is a Bordeaux Table Wine

Thank-you for your help.
My father has had this wine since I was born, and has been saving it for my wedding day, we are not wine experts by far and would like to find out all we can on this wine. Thanks again.
