Next holiday season, you might consider buying your presents without US dollars. When you decide to buy something, you can also choose what you buy it with. Its legal in the US to create our own currencies and exchange systems, and use them for trade as long as no one confuses the created currency with US Federal Reserve Notes, and any taxes owed from transactions can be paid in US currency.
Theres a historical precedent.
Thousands of years ago, our ancestors were using talents, minas, shekels, bekas, gerahs, pims and kesitahs. That weight-based, precious metal system might make any modern gold standard advocate happy. However, even though shekel means weight in Hebrew, this basic unit of silver could weigh anywhere from 9.56 grams upward (for more info, see Biblical Currency).
There were at least three kinds of shekels merchants rate (over la-socher), sanctuary weight (ha-kodesh), and kings stone (beven ha-melech).
And currency values varied by time period.
During the early Roman rule of Palaestina, for example, five gerahs made a talent, four talents a shekel, two shekels a beka, and 25 beka made one mina.
After Bar Kochba and the Temples destruction, however, one talent equaled 60 minas, which equaled 3,000 shekels, 6,000 zuzim, 12,000 sela and 24,000 perutahs.
Today in Israel, one shekel equals 100 agurot. Period.
