Thanks nacl01!
While I ponder at least for a few minutes what is backing the currency of our country, it raises a question in my mind why does it just have to be one precious metal? Namely Gold.
WHY cannot it be a couple of different ones like Platinum for example? Could there be more than one stockpile of precious metals ? A combination Gold, platinum and silver in enough volume might be sufficient in availability to do the job so it all isn't just dependent on always having to find more gold..
Just thinking out loud but I question why only Gold?
