 the Spanish and U.S. silver dollars circulated side by side in the United States. The coinage of various English colonies also circulated. The lion dollar was popular in the Dutch New Netherland Colony (New York), but the lion dollar also circulated throughout the English colonies during the seventeenth and early eighteenth centuries. Examples circulating in the colonies were usually worn so that the design was not fully distinguishable, thus they were sometimes referred to as "dog dollars".

The U.S. dollar was created and defined by the Coinage Act of 1792. It specified a "dollar" to be between 371 and of silver (depending on purity) and an 'eagle" to be between 247 and of gold (again depending on purity). It set the value of an eagle at 10 dollars, and the dollar at 1/10th eagle. It called for 90% silver alloy coins in denominations of 1, 1/2, 1/4, 1/10, and 1/20; it called for 90% gold alloy coins in denominations of 1, 1/2, 1/4, and 1/10.

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.

In 1900, the bimetallic standard was abandoned and the dollar was defined as of gold, equivalent to setting the price of 1 troy ounce of gold at $20.67. Silver coins continued to be issued for circulation until 1964, when all silver was removed from dimes and quarters, and the half dollar was reduced to 40% silver. Silver half dollars were last issued for circulation in 1969.

 was introduced, which corrected some of the mistakes of the Anthony dollar by having a smooth edge and a gold color, without requiring changes to vending machines that accept the Anthony dollar. However, this new coin has failed to achieve the popularity of the still-existing $1 bill and is rarely used in daily transactions. The failure to simultaneously withdraw the dollar bill and weak publicity efforts have been cited by coin proponents as primary reasons for the failure of the dollar coin to gain popular support. There are indications that the dollar coin's failure was also due to the reluctance of armored transport companies to make the necessary adjustments to handle the new coins, and the government's reluctance to mandate it. The result of the armored carriers' unwillingness to handle the new coins was that they virtually never reached merchants in quantities sufficient to be given out as change on a routine basis, or for retail clerks to become used to handling them.

Early releases of the Washington coin included error coins shipped primarily from the Philadelphia mint to Florida and Tennessee banks. Highly sought after by collectors, and trading for as much as $850 each within a week of discovery, the error coins were identified by the absence of the edge impressions "E PLURIBUS UNUM IN GOD WE TRUST 2007 P". The mint of origin is generally accepted to be mostly Philadelphia, although identifying the source mint is impossible without opening a mint pack also containing marked units. Edge lettering is minted in both orientations with respect to "heads", some amateur collectors were initially duped into buying "upside down lettering error" coins. Some cynics also erroneously point out that the Federal Reserve makes more profit from dollar bills than dollar coins because they wear out in a few years, whereas coins are more permanent. The fallacy of this argument arises because new notes printed to replace worn out notes which have been withdrawn from circulation bring in no net revenue to the government to offset the costs of printing new notes and destroying the old ones. As most vending machines are incapable of making change in banknotes, they commonly accept only $1 bills, though a few will give change in dollar coins.

 code EUR) as a cash currency in 2002, the dollar began to depreciate steadily in value. As U.S. trade and budget deficits continued to increase, the euro started rising in value. By December 2004, the dollar had fallen to new lows against all major currencies; the euro rose above $1.36/€ (under €0.74/$) for the first time, in contrast to previous lows in early 2003 (€0.87/$). In the first quarter of 2004 the U.S. dollar, with the advantage of Federal Reserve's policy of raising the interest rates, regained some standing against all major currencies, climbing from €0.78/$ to €0.84/$. However, all gains were lost in the second half of 2004, and the dollar stood at €0.74/$ at the end of 2004. Since 2002, the only year in which the dollar actually recovered against the euro was 2005. Although some analysts previewed the dollar dropping as far as $1.60/€ (€0.63/$), it finished 2005 with an increase against the euro, climbing to €0.83/$. An interest rate reduction by the Federal Reserve on September 18, 2007, raised the euro's value significantly and caused the dollar to fall below €0.70 one month later, to new record lows.
