The quarter, short for quarter dollar, is a United States coin worth 25 cents, one-quarter of a dollar. The coin sports the profile of George Washington on its obverse, and after 1998 its reverse design has changed frequently. It has been produced on and off since 1796 and consistently since 1831.
The cent, the United States one-cent coin, often called the "penny", is a unit of currency equaling one one-hundredth of a United States dollar. It has been the lowest face-value physical unit of U.S. currency since the abolition of the half-cent in 1857. The first U.S. cent was produced in 1787, and the cent has been issued primarily as a copper or copper-plated coin throughout its history. Due to inflation, pennies have lost virtually all their purchasing power and are often viewed as an expensive burden to businesses, banks, government and the public in general.
The United States Mint is a bureau of the Department of the Treasury responsible for producing coinage for the United States to conduct its trade and commerce, as well as controlling the movement of bullion. It does not produce paper money; that responsibility belongs to the Bureau of Engraving and Printing. The first United States Mint was created in Philadelphia in 1792, and soon joined by other centers, whose coins were identified by their own mint marks. There are currently four active coin-producing mints: Philadelphia, Denver, San Francisco, and West Point.
The United States Mint has minted numerous commemorative coins to commemorate persons, places, events, and institutions since 1848. Many of these coins are not intended for general circulation, but are still legal tender. The mint also produces commemorative medals, which are similar to coins but do not have a face value, and therefore are not legal tender.

Presidential dollar coins are a series of United States dollar coins with engravings of relief portraits of U.S. presidents on the obverse and the Statue of Liberty on the reverse.
The American Gold Eagle is an official gold bullion coin of the United States. Authorized under the Gold Bullion Coin Act of 1985, it was first released by the United States Mint in 1986. Because the term "eagle" also is the official United States designation for pre-1933 ten dollars gold coins, the weight of the bullion coin is typically used when describing American Gold Eagles to avoid confusion. This is particularly true with the 1/4-oz American Gold Eagle, which has a marked face value of ten dollars.
The American Platinum Eagle is the official platinum bullion coin of the United States. In 1995, Director of the United States Mint Philip N. Diehl, American Numismatic Association President David L. Ganz, and Platinum Guild International Executive Director Jacques Luben began the legislative process of creating the Platinum Eagle. After over two years of work, the 99.95% fine platinum coins were released by the United States Mint in 1⁄10, 1⁄4, 1⁄2 and 1 troy oz denominations. In late 2008, the fractional denominations were discontinued, leaving only the one ounce denomination. The Platinum Eagle is authorized by the United States Congress, and is backed by the United States Mint for weight, content, and purity.
The Sacagawea dollar is a United States dollar coin introduced in 2000, although not minted for general circulation between 2002 to 2008 and again from 2012 onward because of its general unpopularity with the public and low business demand for the coin. These coins have a copper core clad by manganese brass, giving them a distinctive golden color. The coin features an obverse by Glenna Goodacre. From 2000 to 2008, the reverse featured an eagle design by Thomas D. Rogers. Since 2009, the reverse of the Sacagawea dollar has been changed yearly, with each design in the series depicting a different aspect of Native American cultures. These coins are marketed as "Native American dollars".
The American Buffalo, also known as a gold buffalo, is a 24-karat bullion coin first offered for sale by the United States Mint in 2006. The coin follows the design of the Indian Head nickel and has gained its nickname from the American Bison on the reverse side of the design. This was the first time the United States Government minted pure (.9999) 24-karat gold coins for the public. The coin contains one-troy ounce (31.1g) of pure gold and has a legal tender (face) value of US$50. Due to a combination of the coin's popularity and the increase in the price of gold the coin's value has increased considerably. The initial 2006 U.S. Mint price of the proof coin was $800. In 2007 the price was $899.95, $1,410 in 2009, and $2,010 in 2011.
