The dollar was a unit of currency from Spanish colonial times, and was used in colonial America during the late 1600s. The name comes from the Bohemian "thaler" by way of the Dutch term "daler." The Spanish silver dollars or "pieces of eight" were the hard currency used to back paper money prior to the American Revolution (1775), and most Continental currency was finally denominated in dollars. The dollar is the unit of currency named for specific monetary amounts in the US Constitution (1787). The US defined the US dollar as a unit of currency on April 6, 1792, with the definition tied to the Spanish milled dollar. This contained 371 and 1/4 grains of pure silver, or 416 grains of standard silver (1485/1664ths pure).
Regardless of denomination, silver certificates were a form of currency backed dollar-for-dollar with silver bullion on deposit in the US Treasury. Please see the Related Question for a more detailed explanation.
