Interesting insight. I always thought gold/silver coins would be more useful than jewelry. I mean, how can you verify if a ring or necklace is actual gold, but not be able to verify a coin? I guess using the age-old method of density perhaps? do you know what did process to exchange jewelry looked like?
I think it's more that a ring or necklace is more easily scratch tested for hardness, harder to counterfeit, and less valuable individually. If I show up with a gold krugerrand (1oz, approx. $1,800 at today's prices), expecting to get that value or even half, you're not going to give me that value without somehow testing it. A basic density test involves both scales and beaker with water for volume--who's going to ca…
I guess this is one of those things that sound good 'on paper' , but after deeper analysis it's not so straight forward.
Like others said, it's probably easier to trade toilet paper, cans of food or cigarettes than ounces of gold.
