Is any body buying these? One gold back has one thousandth of a troy ounce of gold within the bill. Bills come in 1, 5, 10, 25, and 50 denominations. The idea is to make gold practical for small transactions, that is from around a few dollars and higher. To me, the idea makes a lot of sense as the currency becomes worth less and less. Go to goldback.com and tell me what you think.
