Where to sell liquor - VSOP, Martell, Hennessy?

I have 7 bottles of hard liquor which are passed down from my grandparents, very old...Is there any shop I can sell to?|||You may be able to exchange those bottles for some other product at a liquor store if the bottles have the new label on them. If not, the bottles may have "antique value" to a collector if they have not been opened.
