The provenance has been based on my reputation.....my word. As far as the returns, I am not going to answer that directly.
But here are a few examples of more recent occurances to make a point.
RA Coronas in Cabs. These were extremenly rare during the boom, and commanded excellent prices. They were recently re-release bring the prices back down to earth. Aficionados started to re-discover this cigar, and these started to disappear off retailers shelves. They sold for just under $300 a cab. Now that they are being discontinued, they have now doubled in price just in the past year, and cannot be found anywhere.
LCG Sabrosos is another example. Now selling for around a 100% mark up from what they normally sold for since going on the discontinued list. This too in just the past year. How many other investments have a 100% return in one year?
Do I invest in cigars? Well yes and no. It just happens that most of my collection has appreciated in value dramatically over the years. It also helps that I have been doing this for years, and have developed many friends and network extensively. However, that being said, I am currently buying boxes of cigars that have been discontinued.....cigars that have been scarce and rare during the boom, cigars that are made in small quantities to begin with, and cigars that have that "classic havana flavor".....and are classics in their own right. I am storing these for the decades, to enjoy myself over the years, and to sell a few off to keep on financing my hobby.
