I've been buying some vintage tobacco on e-bay lately, mainly old versions of OTC stuff like Velvet and Prince Albert. In the process I've been following some of the stuff that's a bit out of my price range as well. Check this out:

Out of Production SEALED Tin of Balkan Sobranie 759 Mixture | eBay

Balkan Sobranie 759 - bidding at this writing is $355 for a 100g tin. There are a few days left so I bet it will go over $400. I wish I could go back in time about 30 years and buy up a bunch of this stuff to pad my retirement! (and microsoft stock for that matter)
