3. A symbol of commercialism or greed; or; SYN. dollar mark, dollar sign.
4. The basic monetary unit in many countries (Canada, Australia, etc.); equal to 100 cents.
Monetary unit of several countries. In the US the dollar, which contains 100 cents, was adopted 1785 and is represented by the symbol “$.” US dollars originally were issued as gold or silver coins; today both metal and paper dollars circulate, but paper predominates. Australia, Canada, and Hong Kong are among the other countries that use the dollar unit, but none of these dollars is equivalent in value to the US dollar.
The US dollar emerged from World War II as the standard currency for international trade. Commodities, even if priced in other currencies, were valued at the prevailing dollar exchange rate. Rising US imports, especially of oil, and government spending resulted in large numbers of dollars held in foreign hands with the resultant devaluation of the dollar by the 1980s. The German mark and the Japanese yen are increasingly important as trading currencies.
