If you paid your employees with 50.00 (US Backed) gold eagles instead of 1 dollar bills what is the difference?
Well, the $50 (nominal value) coins were worth lots more than face value in recent times. It would be very interesting to see what the US government would do if people were paid in US eagles, and declared income in the face value of the US coinage given to them, paying the appropriate tax on the stated face value. Very interesting, indeed.
