Churchill's Port - 1982 - what's it worth?

[jamiebae]

As my grandfather is moving house I need to figure out what to do with a case of the bove which has been stored in his cellar. The case is sealed, and it has been correctly stored since it was purchased but I can't find much info online as to what I should do with it - drink it, sell it or keep it?

I don't really drink port as I struggle to get through a bottle before it starts to go off but if it's worthless I'll obviously give it a try!

So, over to you guys, is Bebs around?
