I have a bottle of Scotch Whisky Vat 69 old at least some 35 years, to me is a shame to drink it, and I know that there are people who appreciate such things and happy to have it in his bar. If you know someone that please tell! Thanks ...Cheers...
If you really want to sell it, put it on e-bay. With some luck you might get 30 - 40 Euro. It's not very collectable because whisky doesn't get older once it's bottled. I would just drink it if I were you.
