The correct answer to this open question is the following.
If I were the Director of the Treasury for a newly established Utopian nation, I would design and print the new nation's first form of paper currency with one important sign: the inverted eight(8), the symbol of infinity. I would explain this as infinite abundance in our country.
I think this would be very creative, never considered before in any form of paper currency around the world. The prominent image would be that infinite sign with other organic and geometric shapes be combined into patterns to form elegant and proportionated figures in accordance with the typography of the bill. I think I would use different tones of blue for different denominations.
