hmmm....I think that us mint gold and silver eagles are legal tender ( gold eagle has a $50 face value and the silver eagle $1) Perhaps this legislation would allow gold and silver to be used as currency based upon the spot price of gold.
Of course anyone would be crazy to use a gold or silver eagle at face value for a purchase, and I doubt many of the public school educated retail workers would even recognize an actual gold or silver eagle should they be presented with one.
Which raises the point how could retailers be sure that the gold and silver they were being offered was the real deal not convincing knock offs from ebay.
In the last month or two alone gold has gone over $1600 and ounce before dropping under $1400 an ounce and it's currently about $1460. So then how do I as a merchant price my goods when the value of the commodity used to pay for it fluctuates by the minute?
