The Dollar - Moruzzi Numismatica Roma

The dollar is the name of the official currency of various states and territories, including Australia, Canada, Eastern Caribbean, Liberia, Hong Kong, New Zealand, Singapore and United States. Its symbol - $ - is usually placed in front of the figure (in Canada, in French language, it's placed generally after). There are different versions about the origin of this symbol: the most accepted argues that it comes from the Pillars of Hercules, represented on Spanish colonial coins. The current name derives from another Anglophone and Central European ancient currency, the thaler (tolar in Bohemia, Thaler in Germany and edaler in Sweden) circulating in several European countries since the sixteenth century. The coin that spread greatly is the United State dollar, the official currency of the United States of America. For a century, more or less, it is also widely used as a reserve currency outside the United States. The dollar is the monetary unit of United States from July the 6th 1785. It was the first time that a nation adopted a decimal system for its currency. Some nations outside the jurisdiction of United States use the U.S. dollar as official currency: Ecuador, Palau, East Timor, Panama and the Federated States of Micronesia. Argentina used a fixed exchange rate of 1:1 between the Argentine peso and the U.S. dollar from 1991 to 2002. The exchange rate of the Hong Kong dollar remained fixed until the early eighties, and the Renminbi, the currency with legal tender in the People's Republic of China, was informally anchored to the dollar since the middle of nineties. The dollar is also used as standard currency unit in international markets for goods quotations such as gold and oil.
