Has anyone out there heard of the Amero?could this replace the dollar?

I think that this is a 'conspiracy theory'. There is certainly something that has been proposed as a 'North American Currency Unit' (involving and incorporating the currencies of Canada, the USA and Mexico and following the model of the 'Euro') but none of the governments involved have expressed any real interest in this. Wikipedia's article is probably quite accurate and equinamical: http://en.wikipedia.org/wiki/North_American_currency_union I cannot see any reason why any geographical entity would want to establish their own monetary unit except for 'local' and 'boundary' reasons. It would make sense, for example, if Canadian and Mexican nationals could expect a fixed exchange rate between the USD, CAD and Mexican Peso (the same could apply to any mix of currencies you cared to mention ... what about the Philippino peso, for example?) I think there is no reason to be afraid of the 'Amero' - mostly because it's not a reality but also because, if it existed, it would tend to stabilise currencies around the world.
