The Amero - North American Currency

I highly doubt this would ever happen (this must be a fake). USA would let the dollar fall to record lows and still continue using it even if its worthless. Consider the amount of AMERO coins and bills that they have to produce, and even if that was an easy task, what would the rate of this currency be (most likely average of all 3). Still, America is too proud a country to ever give up on their dollar bill and include themselves in on any other joint currency.
