Gold is infinitely divisible. You can melt gold and pay somebody any weight of gold you can cast or scrape off. When you are at the point where dollars are good for nothing but toilet paper and a one-million dollar bill buys dinner, gold becomes money. A lot of people think they can't subdivide a one-ounce gold piece. All you need is a file to scrape off as much weight of gold as you need for any transaction or you can melt the thing down and melt off little bbs of gold for daily transactions like a tank of gas. The least of my worries would be how to pay somebody their 1/100th ounce of gold.
Good points.
Question on how to get possession of ounce bars. Having them shipped by one of the gold peddlers on FNC would seem to give notice to gubmit who is holding gold or silver.
