The "Dollar Sign" is a symbol used to represent currency, particularly the United States dollar. It is denoted by the character "$" and is commonly placed before the amount to indicate that it is a monetary value. The symbol has its origins in the Spanish peso, which was widely used in trade during the 18th century. In addition to the U.S. dollar, the dollar sign is also used for other currencies, such as the Canadian dollar and Australian dollar. It is recognized globally and often appears in financial documents, pricing, and accounting to signify amounts of money.
