Remember gold was once used directly as currency. Its been a very long time but if we were to do so again the value of gold would drop quite drasticly. The USD used to base it value on the amount of gold was held in the country. But since then the USD has dropped in value dismaly because it just keeps getting printed. Theres more and more so as the amount in existence increases the value keeps getting flushed. If more gold were mined to keep up it wouldnt be tanking so hard. Unfortunatly there is only so much to be found.
I'm glad gold is rare and can't be devalued by the crooks and banksters....!
If gold was used as a currency, the value wouldn't drop, all to the contrary - it would have to be revaluated many, many times higher.
