This guy has Figured It Out. I learned quite a lot from the article. http://www.bisonprepper.blogspot.com/2016/03/barter-stuff.html My choice so far has been to store cigarette papers for barter, but I may buy and store some of this pipe tobacco now. Got to look at the rolling machines he recommends too. The guy points out that rolled cigarettes store much better than bulk tobacco. Both physically and for bartering purposes. Very hard to make cigarettes with dried-out tobacco. But dried-out pre-rolled cigarettes are still a highly barterable item. Also I read in the comments that cigarette papers can be used to make black powder cartridges. Didn't realize that. Hate to think that could be needful. But it does no harm to know it.
