This is also a big issue wrt:the underworld economy, where the US $ is held because of the large denomination bills availible combined with the high valuation of the currency itself. Supposedly 30% of all availible US bills are in the hands of the grey+black market.

And some people are nervous they could transition to the Euro, due to the higher valuation bill (IIRC 1000 euro bill v.s. $500 bill is the top, but could be wrong - just know that there is a larger euro bill than $ bill) kicking the dollar out of it's place as compact and portable.

Talk about a double whammy...
