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 [1]. I know having a pack of cigarettes would be pretty useful for bartering [2]. Things tend to revert back to commodity money [3], or basically prison currency [4], 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.
Just to add to this, the CDC put out a report last updated a few days ago saying that the risk of contracting COVID from touching a contaminated surface was less than 1 in 10,000 [1]. Importantly, that’s not just a random surface, that’s a surface known to have coronavirus on it. That said, it’s smart to avoid touching your face.
