Hard to say because there are so many variables. I have never actually sold a bottle and I have some in my cellar that could be sold for big profits. Something around the $10K range for a bottle would at least peak my curiosity. Lets say I had a bottle of DRC RC that I got for a song and was now selling for $15K. Would I rather have 1 bottle of DRC RC for $15K or a couple bottles each of Coche, Roulot, Rousseau, etc. I would take the latter all day because I think they are on the same level and sometimes better than DRC for me.
I made the SQN list a couple of years ago. Don't care for the wines so I passed. I'm sure I could have flipped for some profit each release but that just doesn't appeal to me.
