I was going through my dad's liquor cabinet and I found a bottle of
crown royal from 1968!!! He thinks it was a gift at his first
wedding... but 2 wives, 4 kids, and about 150 pounds later.... the seal
is still in tact... the box is just a little dusty. Does anyone know
how much this might be worth or where I can find out?

Thanks in advance.
