- 50 State Quarters
The 50 State Quarters program (Pub.L. 105-124, 111 Stat. 2534, enacted December 1, 1997) is the release of a series of circulating commemorative coins by the United States Mint. Between 1999 and 2008, it featured each of the 50 U.S. states on unique designs for the reverse of the quarter.
In 2009, the U.S. Mint started issuing quarters under the 2009 District of Columbia and U.S. Territories Program, authorized by the passage of H.R. 2764. This program features the District of Columbia, Puerto Rico, American Samoa, Guam, the U.S. Virgin Islands, and Northern Mariana Islands. While the Territories Quarter Program is authorized under a different legislative Act, it is typically seen as an extension of the 50 State Quarters program.
The program was conceived as a means of creating a new generation of coin collectors, and in that it succeeded. The 50 State Quarters program became the most successful numismatic program in history, with roughly half of the U.S. population collecting the coins, either in casual manner or as a serious pursuit. The U.S. federal government so far has made additional profits of $3.0 billion from collectors taking the coins out of circulation.
Treasury Opposition and Congressional Enactment
The program's origins lie with the Citizens Commemorative Coin Advisory Committee (CCCAC), which was appointed by Secretary of Treasury Lloyd Bentsen in December 1993 and chaired by Mint Director Philip N. Diehl. From the first days of the CCCAC, one of its members, David Ganz, urged the committee to endorse the 50 States Quarters program, and in 1995, the CCCAC did so. The committee then sought the support of Representative Michael Castle (R-Delaware), chairman of the House Banking subcommittee with jurisdiction over the nation's coinage. Mr. Castle's initial caution was resolved when the Mr. Diehl suggested the coins be issued in the order the States entered the Union. (Delaware was the first state to ratify the Constitution). Mr. Castle subsequently held hearings and filed legislation to authorize the program.
Despite the support of the Director of the Mint and the Treasury Secretary-appointed CCCAC, the Treasury Department opposed the 50 States Quarters program, citing concerns about the "Disneyfication" of American coinage. The Mint's economic models estimated the program would earn the government between $2.6 billion and $5.1 billion in additional seignorage and $110 million in additional numismatic profits. Mr. Diehl and Mr. Castle used these profit projections to urge Treasury's support, but Treasury officials found the projections to lack credibility. (At the program's conclusion, the Mint estimated the program had earned $3.0 billion in additional seigniorage and $136.2 million in additional numismatic profits.)
Mr. Diehl worked with Mr. Castle behind the scenes to move legislation forward despite Treasury's opposition to the program. In an attempt to derail the legislation, the Treasury suggested to Mr. Castle that the Department conduct a study to determine the feasibility of the program. Such studies are a time-honored device used in Washington to placate proponents of proposals while using the delay to kill them. With Mr. Diehl's advice, Mr. Castle accepted the Treasury offer, and the agreement was codified in the United States Commemorative Coin Act of 1996. The Act also authorized the Secretary to proceed with the 50 States Quarters program without further congressional action if the results of the feasibility study were favorable.
In 1996, the Treasury formed a committee to oversee the feasibility study. No U.S. Mint representatives or outside supporters of the program were appointed. However, several Treasury staff who knew the conclusions Treasury sought were included. The Department engaged the consulting firm Coopers and Lybrand to conduct the study which, to Treasury's dismay, confirmed the Mint's demand, seigniorage and numismatic profit projections for the program. Among other conclusions, the study found that 98 million Americans were likely to save one or more full sets of the quarters. (At the program's conclusion, the Mint estimated that 147 million Americans collected the 50 State Quarters.) Nevertheless, the Treasury Department continued to oppose the program and declined to proceed with it without a congressional mandate to do so.
State quarter program
The 50 State Quarters were released by the United States Mint every ten weeks, or five each year. They were released in the same order that the states ratified the Constitution. Each quarter's reverse commemorated one of the 50 states with a design emblematic of its unique history, traditions and symbols. Certain design elements, such as state flags, images of living persons, and head-and-shoulder images of deceased persons, were prohibited.
The authorizing legislation and Mint procedures gave states a substantial role and considerable discretion in determining the design that would represent their state. The majority of states followed a process by which the governor solicited the state’s citizens to submit design concepts and appointed an advisory group to oversee the process. Governors submitted three to five finalist design concepts to the Secretary of Treasury for approval. Approved designs were returned to the states for selection of a final design.
States typically employed one of two approaches in making this selection. In 33 states, the governor selected the final recommended design, often based on the recommendations of advisory groups and citizens. In the other 17 states, citizens selected the final design through online, telephone, mail or other public votes. U.S. Mint engravers executed all final design concepts approved by the Secretary of Treasury. The media and public attention surrounding this process and the release of each state's quarter was intense and produced significant media for the program.
The statehood quarters program was the most popular commemorative coin program in United States history; the United States Mint has estimated that 147 million Americans have collected state quarters and 3.5 million participated in the selection of state quarter designs.
By the end of 2008, all of the original 50 states quarters had been minted and released. The official total, according to the U.S. Mint, was 34,797,600,000 coins. The average mintage was 695,952,000 coins per state, but ranged between Virginia's 1,594,616,000 to Oklahoma's 416,600,000. Demand was stronger for quarters issued early in the program. This was due to weakening economic conditions in later years and the waning of the initial surge of demand when the program was launched. Another factor was the reassertion of the Treasury Department's opposition to the program. When the Director's term ended in 2000, the Treasury proceeded to reduce and finally terminate the most effective elements of the Mint's promotional program despite the high return on investment they earned.

Additional notes on individual designs
- Alabama: The Alabama state quarter is the first coin circulated in the U.S. that features Braille writing. It also is the first coin circulated in the U.S. featuring a member of the Socialist Party.
- Arizona: The banner reading "Grand Canyon State" in the design is intended to split the quarter into two sections and indicate the Grand Canyon and the saguaro cactus are in two different Arizona scenes, as the saguaro cactus is not found near the Grand Canyon.
- Colorado: William Eugene Rollins designed the quarter in a contest held in 2005. The quarter shows the landscape of Colorado's nature side with a mountain and pine trees.
- Connecticut: The Charter Oak on the back of the Connecticut quarter fell during a storm on August 21, 1856. It also appears on a 1936 half dollar commemorating the 300th anniversary of the state's settlement by Europeans.
- District of Columbia: The Mint rejected some of the design narratives that the District government submitted because the Mint deemed the motto "Taxation Without Representation" to be controversial.
- Georgia: an apparent mistake in the outline of the state of Georgia on the quarter appears to have accidentally left out Dade County, which is in the extreme northwestern part of the state.
- Hawaii: The Hawaii quarter features a rendition of the statue of Kamehameha I, who united the Hawaiian Islands in 1810, with the state outline and motto. This is the first and only U.S. coin to feature royalty or a monarch of any kind.
- Illinois: The Illinois quarter is the only quarter to directly reference and portray an urban city, with a picture of the Chicago skyline. It is also the first coin to feature George Washington and Abraham Lincoln on the same coin.
- Indiana: The Indiana quarter—having a problem similar to Georgia's quarter—is missing part of its northwestern corner. Lake County is either partially or completely missing (where it borders with Lake Michigan). The error did not garner considerable notice.
- Iowa: When Iowans were debating the design for its state quarter in 2002, there was a grassroots effort to use a design featuring the Sullivan brothers (to honor the five Waterloo siblings who died when the ship they were aboard—the USS Juneau (CL-52)—sank during the Naval Battle of Guadalcanal, 1942). The effort was ultimately unsuccessful, and a Grant Wood design was used, but not before some copyright issues were resolved.
- Maryland: The Maryland Statehouse featured on the coin is the country's largest wooden dome built without nails. Some residents complained that the quarter did not feature the state's famous blue crab.
- Missouri: The design contest winner for the Missouri quarter, Paul Jackson, has claimed that the Mint engraver needlessly redesigned Jackson's original submission. The Mint stated that Jackson's design was not coinable, but a private mint later demonstrated that it was. It emerged that Mint engravers hold a monopoly on the design of U.S. coinage, and the term "design contest" was dropped from solicitations for ideas for later state quarters.
- Nebraska: One of the final concepts for the Nebraska quarter was based on the Ponca leader Standing Bear, who, in a suit brought against the federal government, successfully argued that Native Americans were citizens entitled to rights under the U.S. Constitution.
- New Hampshire: The Old Man of the Mountain, featured on the back of the New Hampshire quarter, collapsed in 2003.
- Oregon: Oregon's design features a scene of Crater Lake and Wizard Island. This design was chosen by the Oregon Commemorative Quarter Commission. The Quarter Commission was made up of 18 members, including Governor Ted Kulongoski, State Treasurer Randall Edwards, Columbia Sportswear Chairperson Gert Boyle, numismatist Monte Mensing, and Beaverton High School student Laura Davis, along with state legislators Charles Starr, Joan Dukes, Betsy Johnson, and Betsy Close, among others. The Quarter Commission chose the Crater Lake design from three other finalists: a jumping salmon, the Oregon Trail, and Mount Hood.
- South Dakota: Although South Dakota has the second highest proportion of American Indians of any state, the South Dakota quarter features three items that are the result of European settlement. These symbols are Mount Rushmore, which is carved into the Black Hills which are seen as sacred by the Lakota, a pheasant (an exotic species), and wheat, which has replaced tens of thousands of square miles of diverse grasslands.
- Tennessee: There has also been some controversy over the Tennessee quarter. Some sources[who?] claim that the details on the instruments depicted on the quarter are inaccurate, such as the number of strings on the guitar and the location of the tubing on the trumpet.
- West Virginia: During the submission process for the design of the West Virginia quarter, there was an apparent movement to put the famous Mothman on the final design.
- Wisconsin: A number of the Wisconsin quarters featured a small mint error: the ear of corn features an extra leaf. Some of the affected coins feature a "low leaf", others feature a "high leaf". All of these "error coins" were minted at the Denver mint. It is unclear whether the error was deliberate or accidental, but the error has sparked a collector frenzy. Sets of the flawed coins have been sold on eBay for up to $2800.
- Wyoming: Some Wyoming quarters were released in 2007 with indications of inadequate quality control. Many persons, upon first seeing the same cowboy outline design used on the state's automobile license plates, have mistakenly believed that the lack of detail is itself a flaw, the result of an incomplete striking. However, evidence of cracks in the die and subsequent hasty repairs have been observed in a few circulation specimens.
The following map shows the years each state, federal district, or territory is released as a State Quarter. The following table has the quarters grouped by year.

In 1997, Congress passed the 50 States Commemorative Coin Program Act, which ordered the creation of the state quarters series to "honor the unique Federal Republic of 50 States that comprise the United States; and to promote the diffusion of knowledge among the youth of the United States about the individual states, their history and geography, and the rich diversity of the national heritage...", and to encourage "young people and their families to collect memorable tokens of all of the States for the face value of the coins."
While mintage totals of the various designs vary widely—Virginia quarters are almost twenty times more abundant than Northern Marianas quarters—none of the regular circulating issues are rare enough to become a valuable investment.
There was, however, a measure of collector interest and controversy over die errors in the Wisconsin quarter. Some designs feature corn without a smaller leaf, others feature a small leaf pointing upwards, and still others have the leaf bending down. A set of all three quarters from the Philadelphia mint sold on eBay in February 2005 for $300, and have since seen significant increases, such as $1500 for individual coins.
Another die cast error ran with the first Delaware quarters. Being the first model of state quarter made, the mint gave it a disproportionate weight causing machine benders to not accept it. The quarter die was quickly fixed.
A major error occurred in 2000 when the reverse die of a Sacagawea Dollar was combined with the obverse die of a State Quarter on dollar-coin planchets to form what is known as a "mule". Only eleven of these specimens, produced on dollar planchets, escaped from the mint.
A 2005 Minnesota double die quarter, as well as a 2005 Minnesota quarter with extra trees (another die error), have both triggered numismatic interest. An unusual die break on some 2005 Kansas quarters created a humpback bison. Relatively more common are Kansas quarters sporting the motto "IN GOD WE RUST". The 1999 silver proof coinage set is valuable, being the first year of the series and with a relatively small mintage. The set in base metal, of this or any other year, is worth only a fraction as much. The silver proof sets of later years, while having some intrinsic and collector worth, are also priced far lower.
In general, the program increased interest in quarter and general coin collecting. Large numbers of ads, quarter products and quarter information were available during the years the program ran. Home Shopping Network, Franklin Mint, and Littleton Coin Company were among the most prominent in ad space.
Since the 50 State Quarters program was expected to increase public demand for quarters which would be collected and taken out of circulation, the Mint used economic models to estimate the additional seigniorage the program would produce. These estimates established a range of $2.6 billion to $5.1 billion. (At the end of the program, the Mint estimated the actual increase in seigniorage to be $3 billion.) The Mint also estimated the program would earn $110 million in additional numismatic profits. (The final, post-program estimate was $136.2 million.) The Mint used these estimates to support the proposed program, and the legislation enacting the 50 States Quarters program cited these estimates.

- The Late Night with Conan O'Brien television show has aired several segments about fictional satirical designs for new state quarters.
- Sculptor Daniel Carr, whose designs were used for the New York and Rhode Island state quarters and whose concept was adapted for the Maine state quarter, has created a series of parody quarters making light of the state quarter concept.
