We'll see monday how the markets react and then maybe there will be a reaction in the commodities market.
They are legal US money and recognizable by everyone.
My neighbor went with me when I bought them...he bought something called 'silver rounds' that had 99.999 % silver written on them. I asked him who wrote that on them and how many people would believe that in a crisis situation. (assay required?)
That's why I bought US dollars...no questions/doubts about their content.They'll be easy to exchange in reasonable amounts.
