Happens. A couple of years ago, a very prominent collector died and his wife knew the pipes had value, but didn't know about the vintage tobacco. She called a friend of mine to help with selling the pipe collection, then blithely dumped approximately $40,000 worth of vintage tobacco down the trash chute. We're talking mid century Balkan Sobranie, 759, #10 Virginia, Garfinkle's, Sullivan & Powell, 1960's Dunhill blends, Craven Mixture, State Express, Three Nuns, and on, and on. Down the chute.Wow, just....wow.
