(To most, "dollar" is actually US dollar).
Quote from 'Dollar' on wikipedia.org:
"The dollar (often represented by the dollar sign $) is the name of the official currency of many countries, including Canada, the Eastern Caribbean territories, Ecuador, Suriname, El Salvador, the United States, Panama, Belize, Singapore, Hong Kong, Taiwan, Brunei, East Timor, Australia, and New Zealand"
'Most'? are you positive? This may be another instance of American Patrio-Solipsism...
