One of the threads I read maybe a decade ago about Argentina’s financial collapse at the time, was that in hind sight they’d wished they’d bought gold and made adulterated rings out of it. There was a lot of bartering, and most gold jewelry was trading under the assuption it was the most common karet (14?) by weight, and having some rings at a slightly lesser amount (or even the same) would have been way easier than trying to trade pure gold.

I don’t have a sense for how bad things need to get before making your own rings becomes a viable hedge, but I don’t think the US is quite there yet.
