I can't understand. Of what value is it really? It's rare, and shiny sooo.....mankind decides to base it's currency off of it? I genuinely don't understand how it came to represent what it does today. I mean, what purpose does it serve besides jewelry. When did someone say, "I have this good or service to offer, and in return I would like a piece of that shiny rare metal from the ground,"?
I'm genuinely perplexed by precious metals and how they became the base of currency. I could see oil, as it has a practical application, but what are you going to do with gold?
