Is this bottle of wine valuable??

Hi Angel Eyes and welcome to the Wine Board. The wine probably is not worth more than $10 or $12, but I'm more concerned about its drinkability after 21 years. Not all wine ages well, and even those don't age forever. You might find some life in it, but I wouldn't give it as a wedding present for anyone, much less my best friend. Why not buy her a new one?
