THing is, the dollar is no longer tied to gold! I think if they tried that today, they would get more Lead than gold!
Well, seems there are _two_ "dollars": one is the common paper form (and electronic & credit variants) everyone is familiar with (and is devaluing over the long run), and then there is the "dollar" as in the face value on US Mint gold/silver/platinum coins (and whose value is tied to the metals, $20/oz gold and $100/oz platinum, and always has been). If the two conflated "dollars" could be separated & named, interesting days would follow.
