Coinage Act of 1792 in the context of "Legal tender"

The United States dollar (symbol: $; currency code: USD) is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color.

The U.S. dollar was originally defined under a bimetallic standard of 371.25 grains (24.057 g) (0.7734375 troy ounces) fine silver or, from 1834, 23.22 grains (1.505 g) fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, its equivalence to gold was revised to $35 per troy ounce. In 1971 all links to gold were repealed. The U.S. dollar became an important international reserve currency after the First World War, and displaced the pound sterling as the world's primary reserve currency by the Bretton Woods Agreement towards the end of the Second World War. The dollar is the most widely used currency in international transactions, and a free-floating currency. It is also the official currency in several countries and the de facto currency in many others, with Federal Reserve Notes (and, in a few cases, U.S. coins) used in circulation.

The Coinage Act of 1834 was passed by the United States Congress on June 28, 1834. It raised the silver-to-gold weight ratio from its 1792 level of 15:1 (established by the Coinage Act of 1792) to 16:1 thus setting the mint price for silver at a level below its international market price.

The Act redefined the U.S. Eagle coin (ten U.S. Dollars) as containing 232 grains of fine gold, compared to 247.5 grains in the prior Act. This fixed the official basis of the dollar as $20.69 per troy ounce. This standard prevailed until 1933, when the official price rose to $35 as a consequence of the Great Depression.

The concept of liberty has frequently been represented by personifications, often loosely shown as a female classical goddess. Examples include Marianne, the national personification of the French Republic and its values of Liberté, Égalité, Fraternité, and the female Liberty portrayed in artworks, on United States coins beginning in 1793, and many other depictions. These descend from images on ancient Roman coins of the Roman goddess Libertas and from various developments from the Renaissance onwards. The Dutch Maiden was among the first, re-introducing the cap of liberty on a liberty pole featured in many types of image, though not using the Phrygian cap style that became conventional. The 1886 Statue of Liberty (Liberty Enlightening the World) by Frédéric Auguste Bartholdi is a well-known example in art, a gift from France to the United States.

The Philadelphia Mint is a branch of the United States Mint in Philadelphia. It was built in 1792 following the Coinage Act of 1792, in order to establish a national identity and the needs of commerce in the United States, and is the first and oldest national mint.
