Let the bartering begin! That would be the easiest way to keep the gov't out of our collective pocket.
If anyone is familiar with the money exchanges in the Middle East, this is why they have done it for over a thousand years- they codify every transaction so it's hard, in not impossible, to de-cifer. They can take the slip of paper (if it's even on paper) to the person referred to in the transaction and they will handle any payments necessary.
They should have stopped making pennies long ago. Time to start hoarding them, melting them down and selling the copper/zinc/nickel for scrap.
