Question

What is the current market value of an unopened 1961 Seagram's V.O. 1-gallon bottle?

Answer 1

Go find out how much a new one is today, and that's about how much you can expect to get for yours. Unfortuneately their is no rare batch of seagrams. But good luck.

Answer 2

being more of a novelty item you could try sites like ebay or other auction sites. the bottle is most probably more valuable than the liquor inside. But don't empty it as the buyer would probably want the contents for show.
