Selling bottles of whisky ????

[Mike B]

Just new here at the site but I see several posts where different individuals have come across single bottles of old whiskey through various means. Anyways, I assume most of us here are whisky drinkers. Why would anyone be interested in selling off a 40-year-old bottle of whiskey that their grandfather had in the house? It just surprises me that people seem so reluctant to open and drink it, rather than wonder as to it's value (which likely isn't a whole lot of money) and then consider selling it. Just seems a bit strange to me, perhaps others might disagree?
