Gf's dad offered me $150 a couple of years ago, I laughed for quite some time.
A couple of bar owners have asked me which one it is, all I know is what it looks like (sort of; it's wrapped in bubble and in a box these days), it has a felt cover over the stopper and no blemishes. Those bar owners said depending, $500 to $2000, they'd have to see it...
I don't know if I've ever had Courvoisier, isn't cognac kinda harsh like scotch? Hard liquor for sipping was never my thing.
