Unlike the Spanish milled dollar, the Continental Congress and the Coinage Act prescribed a decimal system of units to go with the unit dollar, as follows: the mill, or one-thousandth of a dollar; the cent, or one-hundredth of a dollar; the dime, or one-tenth of a dollar; and the eagle, or ten dollars.

Even after the United States Mint commenced issuing coins in 1792, locally minted ''dollars'' and ''cents'' were less abundant in circulation than Spanish American ''pesos'' and ''reales''; hence Spanish, Mexican and American dollars all remained legal tender in the United States until the Coinage Act of 1857. In particular, Colonists' familiarity with the Spanish two-''real quarter peso'' was the reason for issuing a quasi-decimal 25-cent quarter dollar coin rather than a 20-cent coin.

Coinage Act of 1792
On July 6, 1785, the Continental Congress resolved that the money unit of the United States, the dollar, would contain 375.64 grains of fine silver; on August 8, 1786, the Continental Congress continued that definition and further resolved that the money of account, corresponding with the division of coins, would proceed in a decimal ratio, with the sub-units being mills at 0.001 of a dollar, cents at 0.010 of a dollar, and dimes at 0.100 of a dollar.

s of fine silver, or of "standard silver" of fineness 371.25/416 = 89.24%; as well as an "eagle" to contain grains of fine gold, or of 22 karat or 91.67% fine gold. Alexander Hamilton arrived at these numbers based on a treasury assay of the average fine silver content of a selection of worn Spanish dollars, which came out to be 371 grains. Combined with the prevailing gold-silver ratio of 15, the standard for gold was calculated at 371/15 = 24.73 grains fine gold or 26.98 grains 22K gold. Rounding the latter to 27.0 grains finalized the dollar's standard to 24.75 grains of fine gold or 24.75*15 = 371.25 grains = 24.0566 grams = 0.7735 troy ounces of fine silver.
The same coinage act also set the value of an eagle at 10 dollars, and the dollar at eagle. It called for silver coins in denominations of 1, , , , and dollar, as well as gold coins in denominations of 1, and eagle. The value of gold or silver contained in the dollar was then converted into relative value in the economy for the buying and selling of goods. This allowed the value of things to remain fairly constant over time, except for the influx and outflux of gold and silver in the nation's economy.
Though a Spanish dollar freshly minted after 1772 theoretically contained 417.7 grains of silver of fineness 130/144 (or 377.1 grains fine silver), reliable assays of the period in fact confirmed a fine silver content of for the average Spanish dollar in circulation.
The new U.S. silver dollar of therefore compared favorably and was received at par with the Spanish dollar for foreign payments, and after 1803 the United States Mint had to suspend making this coin out of its limited resources since it failed to stay in domestic circulation. It was only after Mexican independence in 1821 when their peso's fine silver content of 377.1 grains was firmly upheld, which the U.S. later had to compete with using a heavier Trade dollar coin.
Design
The early currency of the United States did not exhibit faces of presidents, as is the custom now; although today, by law, only the portrait of a deceased individual may appear on United States currency. In fact, the newly formed government was against having portraits of leaders on the currency, a practice compared to the policies of European monarchs. The currency as we know it today did not get the faces they currently have until after the early 20th century; before that "heads" side of coinage used profile faces and striding, seated, and standing figures from Greek and Roman mythology and composite Native Americans. The last coins to be converted to profiles of historic Americans were the dime (1946) and the Dollar (1971).

Continental currency depreciated badly during the war, giving rise to the famous phrase "not worth a continental". A primary problem was that monetary policy was not coordinated between Congress and the states, which continued to issue bills of credit. Additionally, neither Congress nor the governments of the several states had the will or the means to retire the bills from circulation through taxation or the sale of bonds. The currency was ultimately replaced by the silver dollar at the rate of 1 silver dollar to 1000 continental dollars. It gave rise to the phrase "not worth a continental", and was responsible for the clause in article 1, section 10 of the United States Constitution which reads: "No state shall... make anything but gold and silver coin a tender in payment of debts".

Subsequent to the
Coinage Act of 1834
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 le ...
the dollar's fine gold equivalent was revised to 23.2 grains; it was slightly adjusted to in 1837 (gold-silver ratio ~16). The same act also resolved the difficulty in minting the "standard silver" of 89.24% fineness by revising the dollar's alloy to 412.5 grains, 90% silver, still containing 371.25 grains fine silver. Gold was also revised to 90% fineness: 25.8 grains gross, 23.22 grains fine gold.
Following the rise in the price of silver during the California Gold Rush and the disappearance of circulating silver coins, the Coinage Act of 1853 reduced the standard for silver coins less than $1 from 412.5 grains to , 90% silver per 100 cents (slightly revised to 25.0 g, 90% silver in 1873). The Act also limited the free silver right of individuals to convert bullion into only one coin, the silver dollar of 412.5 grains; smaller coins of lower standard can only be produced by the United States Mint using its own bullion.

* In silver: half dime, dime, quarter dollar, half dollar, silver dollar.

, which did not bear interest but could be redeemed on demand for precious metals. However, by December 1861, the Union government's supply of specie was outstripped by demand for redemption and they were forced to suspend redemption temporarily. In February 1862 Congress passed the ''Legal Tender Act of 1862'', issuing United States Notes, which were not redeemable on demand and bore no interest, but were legal tender, meaning that creditors had to accept them at face value for any payment except for public debts and import tariffs. However, silver and gold coins continued to be issued, resulting in the depreciation of the newly printed notes through Gresham's Law. In 1869, Supreme Court ruled in Hepburn v. Griswold that Congress could not require creditors to accept United States Notes, but overturned that ruling the next year in the Legal Tender Cases. In 1875, Congress passed the '' Specie Payment Resumption Act'', requiring the Treasury to allow U.S. Notes to be redeemed for gold after January 1, 1879.
Gold standard, 20th century
Though the dollar came under the
gold standard
A gold standard is a Backed currency, monetary system in which the standard economics, economic unit of account is based on a fixed quantity of gold. The gold standard was the basis for the international monetary system from the 1870s to the ...
''de jure'' only after 1900, the bimetallic era was ended ''de facto'' when the Coinage Act of 1873 suspended the minting of the standard silver dollar of 412.5 grains (26.73 g = 0.8595 oz t), the only fully legal tender coin that individuals could convert bullion into in unlimited (or Free silver) quantities, and right at the onset of the silver rush from the Comstock Lode in the 1870s. This was the so-called "Crime of '73".
The '' Gold Standard Act'' of 1900 repealed the U.S. dollar's historic link to silver and defined it solely as of fine gold (or $20.67 per
troy ounce
Troy weight is a system of units of mass that originated in 15th-century England, and is primarily used in the precious metals industry. The troy weight units are the grain, the pennyweight (24 grains), the troy ounce (20 pennyweights), and ...
of 480 grains). In 1933, gold coins were confiscated by Executive Order 6102 under Franklin D. Roosevelt, and in 1934 the standard was changed to $35 per troy ounce fine gold, or per dollar.
After 1968 a series of revisions to the gold peg was implemented, culminating in the Nixon Shock of August 15, 1971, which suddenly ended the convertibility of dollars to gold. The U.S. dollar has since floated freely on the foreign exchange markets.

Coins
The United States Mint has issued legal tender coins every year from 1792 to the present. From 1934 to the present, the only denominations produced for circulation have been the familiar penny, nickel, dime, quarter, half dollar, and dollar.
Gold and silver coins have been previously minted for general circulation from the 18th to the 20th centuries. The last gold coins were minted in 1933. The last 90% silver coins were minted in 1964, and the last 40% silver half dollar was minted in 1970.

The U.S. Constitution provides that Congress shall have the power to "borrow money on the credit of the United States." Congress has exercised that power by authorizing Federal Reserve Banks to issue Federal Reserve Notes.

Notes in denominations of $500, $1,000, $5,000, $10,000, and $100,000 were all produced at one time; see large denomination bills in U.S. currency for details. With the exception of the $100,000 bill (which was only issued as a Series 1934 Gold Certificate and was never publicly circulated; thus it is illegal to own), these notes are now collectors' items and are worth more than their face value to collectors.
Though still predominantly green, the post-2004 series incorporate other colors to better distinguish different denominations. As a result of a 2008 decision in an accessibility lawsuit filed by the American Council of the Blind, the Bureau of Engraving and Printing is planning to implement a raised tactile feature in the next redesign of each note, except the $1 and the current version of the $100 bill. It also plans larger, higher-contrast numerals, more color differences, and distribution of currency readers to assist the visually impaired during the transition period.

The adjusted monetary base has increased from approximately $400 billion in 1994, to $800 billion in 2005, and to over $3 trillion in 2013.
When the Federal Reserve makes a purchase, it credits the seller's reserve account (with the Federal Reserve). This money is not transferred from any existing funds—it is at this point that the Federal Reserve has created new high-powered money. Commercial banks then decide how much money to keep in deposit with the Federal Reserve and how much to hold as physical currency. In the latter case, the Federal Reserve places an order for printed money from the U.S. Treasury Department. The Treasury Department, in turn, sends these requests to the Bureau of Engraving and Printing (to print new dollar bills) and the Bureau of the Mint (to stamp the coins).
The Federal Reserve's monetary policy objectives to keep prices stable and unemployment low is often called the ''dual mandate''. This replaces past practices under a

The value of the U.S. dollar declined significantly during wartime, especially during the
American Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by state ...

Federal Reserve
The Federal Reserve System (often shortened to the Federal Reserve, or simply the Fed) is the central banking system of the United States of America. It was created on December 23, 1913, with the enactment of the Federal Reserve Act, after a ...
, which was established in 1913, was designed to furnish an "elastic" currency subject to "substantial changes of quantity over short periods", which differed significantly from previous forms of high-powered money such as gold, national banknotes, and silver coins. Over the very long run, the prior gold standard kept prices stable—for instance, the price level and the value of the U.S. dollar in 1914 were not very different from the price level in the 1880s. The Federal Reserve initially succeeded in maintaining the value of the U.S. dollar and price stability, reversing the inflation caused by the First World War and stabilizing the value of the dollar during the 1920s, before presiding over a 30% deflation in U.S. prices in the 1930s.
Under the Bretton Woods system established after World War II, the value of gold was fixed to $35 per ounce, and the value of the U.S. dollar was thus anchored to the value of gold. Rising government spending in the 1960s, however, led to doubts about the ability of the United States to maintain this convertibility, gold stocks dwindled as banks and international investors began to convert dollars to gold, and as a result, the value of the dollar began to decline. Facing an emerging currency crisis and the imminent danger that the United States would no longer be able to redeem dollars for gold, gold convertibility was finally terminated in 1971 by President Nixon, resulting in the " Nixon shock".
The value of the U.S. dollar was therefore no longer anchored to gold, and it fell upon the Federal Reserve to maintain the value of the U.S. currency. The Federal Reserve, however, continued to increase the money supply, resulting in stagflation and a rapidly declining value of the U.S. dollar in the 1970s. This was largely due to the prevailing economic view at the time that inflation and real economic growth were linked (the Phillips curve), and so inflation was regarded as relatively benign. Between 1965 and 1981, the U.S. dollar lost two thirds of its value.

appointed Paul VolckerChairman of the Federal Reserve. The Federal Reserve tightened the money supply and inflation was substantially lower in the 1980s, and hence the value of the U.S. dollar stabilized.
Over the thirty-year period from 1981 to 2009, the U.S. dollar lost over half its value. This is because the Federal Reserve has targeted not zero inflation, but a low, stable rate of inflation—between 1987 and 1997, the rate of inflation was approximately 3.5%, and between 1997 and 2007 it was approximately 2%. The so-called " Great Moderation" of economic conditions since the 1970s is credited to monetary policy targeting price stability.
There is an ongoing debate about whether central banks should target zero inflation (which would mean a constant value for the U.S. dollar over time) or low, stable inflation (which would mean a continuously but slowly declining value of the dollar over time, as is the case now). Although some economists are in favor of a zero inflation policy and therefore a constant value for the U.S. dollar, others contend that such a policy limits the ability of the central bank to control interest rates and stimulate the economy when needed.
