I have a few ounces of silver, but there’s some articles about various government/currency collapses that make me think some other items may be equally or more valuable. In Russia they started using American dollars, British pounds, or vodka . I know having a pack of cigarettes would be pretty useful for bartering . Things tend to revert back to commodity money , or basically prison currency , and any item in your preps could potentially very valuable to someone who doesn’t have it. But I’d think if there’s some kind of large exchange (say, I want your boat) having gold may be easier to deal with than dozens of cartons of cigarettes.
