Also, most currency is already color coded. It is amazing the number of newspaper articles I have seen about this that claim that all American currency is the same color.

Huh? All American currency is the same from denomination to denomination within each series. Where does the color variation come in?

They want to be able to differentiate denominations by color (e.g. orange for tens, green for twenties, blue and red for fifties.)
