The50 State quarters (authorized byPub. L. 105–124 (text)(PDF), 111 Stat. 2534, enactedDecember 1, 1997) were a series ofcirculating commemorativequarters released by theUnited States Mint. Minted from 1999 through 2008, they featured unique designs for each of the 50US states on thereverse.
The 50 State Quarters Program was started to support a new generation ofcoin collectors,[1][2] and it became the most successfulnumismatic program in US history, with roughly half of theUS population collecting the coins, either in a casual manner or as a serious pursuit.[3] TheUS federal government so far has made additional profits of $3 billion from collectorstaking the coins out of circulation.[4]
In 2009, the US Mint began issuing quarters under the 2009District of Columbia and US Territories Program. The Territories Quarter Program was authorized by the passage of a newer legislative act,H.R. 2764. This program features theDistrict of Columbia,Puerto Rico,American Samoa,Guam, theUnited States Virgin Islands, and theNorthern Mariana Islands.[5]
The 50 State Quarters program was initially inspired by a 1992Royal Canadian Mint program, "Canada 125", marking the 125th anniversary of the country'sConfederation with a series of commemorative25-cent pieces representing each of its 12 (at the time) provinces and territories. The Canada 125 program sparked a revival of interest in coin collecting among Canadians, which led American numismatists to advocate for the United States Mint to create a similar series of coins representing U.S. states.[6][7]
In 1992, Congress passed the 1996 Atlanta Centennial Olympic Games Commemorative Coin Act. In addition to authorizing a series of commemorative coins marking the1996 Summer Olympics, the law also established theCitizens Commemorative Coin Advisory Committee (CCCAC) to consider ideas for future releases.[8] AfterTreasury SecretaryLloyd Bentsen appointed the committee in December 1993, several of its members, led by David Ganz, urged the committee to endorse a state quarters program. Initially, Ganz found support from only Charles Atherton, from the Federal Commission on Fine Arts, and Dan Hoffman, a young numismatist from South Carolina who also served on the CCCAC. However, by 1995, the CCCAC finally endorsed the idea. The committee then sought the support of RepresentativeMichael Castle (R-Delaware), chairman of theHouse Banking subcommittee with jurisdiction over thenation's coinage. Castle's initial caution was resolved when Diehl suggested the coins be issued in the order the states entered the Union orratified the Constitution. Delaware, Castle's home state, was the first state to ratify the Constitution, and would thus get to be the first state to have its quarter released. Castle subsequently held hearings and filed legislation to authorize the program.[9]
Despite the support of the director of the mint and the Treasury Secretary-appointed CCCAC, the Treasury Department opposed the 50 States Quarters Program, as commemorative coinage had come to be identified with abuses and excesses.[10] The Mint'seconomic models estimated the program would earn the government between $2.6 billion and $5.1 billion in additionalseignorage and $110 million in additional numismatic profits. Diehl and Castle used these profit projections to urge the 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 billion in additional seignorage and $136.2 million in additional numismatic profits).[4]
Diehl worked with Castle behind the scenes to move legislation forward despite the Treasury's opposition to the program.[1][11] However, the Treasury suggested to Castle that the department should conduct a study to determine the feasibility of the program. With Diehl's advice, Castle accepted the Treasury's offer, and the agreement was codified in theUnited States Commemorative Coin Act of 1996.[12][13] 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.
The Treasury Department engaged the consulting firmCoopers and Lybrand to conduct the study in 1997, which confirmed the Mint's demand, seignorage, and numismatic profit projections for the program.[10] 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.[4]
In 1997, Congress issued that mandate in the form ofS. 1228, the 50 States Commemorative Coin Program Act, which was signed into law byPresidentBill Clinton on December 1, 1997.
The 50 State quarters were released by theUnited States Mint every ten weeks, or five each year. They were released in the same order that thestates ratified the Constitution or were admitted to the Union. Each quarter'sreverse commemorated one of the 50 states with a design emblematic of its unique history, traditions, andsymbols. Certain design elements, such asstate flags, images of living persons, and head-and-shoulder images of deceased persons were prohibited.
The authorizing legislation and Mint procedures gave each state a substantial role and considerable discretion in determining the design that would represent their state. The majority of states followed a process by which thegovernor 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 the Treasury for approval. Approved designs were returned to the states for selection of a final design.
States usually 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. US Mint engravers applied all final design concepts approved by the Treasury Secretary. The media and public attention surrounding this process and the release of each state's quarter was intense and produced significant publicity for the program.[4][14]
In several cases, the process of creating and finalizing a design caused controversy in the represented state, with people and groups expressing disappointment that the design did not properly reflect their state. There were disputes over which state could lay claim to certain design elements that appeared in other states, such as an ear of corn or the Rocky Mountains. The Mint's conversion of each state's proposal into the final design that was used on the quarter also drew criticism for being overly simplified or poorly rendered.[15] Paul Jackson, whose design was chosen for the Missouri quarter and then pared down by the Mint, led a series of protests which included placing stickers with Jackson's original design on the reverses of 250,000 quarters and distributing them nationwide.[16][17] In response to these criticisms, the Mint established theArtistic Infusion Program in 2003, hiring more professional artists and engravers to create better-looking designs for all commemorative coins.[15]
The 50 State Quarters Program was the most popular commemorative coin program in theUnited 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.[4]
By the end of 2008, all of the original 50 States quarters had been minted and released. The official total, according to the US Mint, was 34,797,600,000 coins. The averagemintage was 695,952,000 coins per state, but ranged from 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 toweakening economic conditions in later years and the waning of the initial surge ofdemand 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.[citation needed]

In 1997,Congress passed the 50 States Commemorative Coin Program Act, which instructed the creation of the 50 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."[41]

While mintage totals of the various designs vary widely—Virginia quarters are almost 20 times as abundant as the 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 overdie errors in the Wisconsin quarter. Some designs from the Denver mint feature corn without a smaller leaf, others feature a small leaf pointing upwards, and still others have the leaf bending down.[42] A set of all three quarters sold oneBay in February 2005 for $300 and initially saw significant increases, such as $1500 for individual coins, but as of February 2020PCGS lists the value of MS-62 specimens from $92 to $130 each.[43]
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 vending machines to not accept it. The quarter die was quickly fixed. Some Delaware quarters appeared without the lastE, now saying, "THE FIRST STAT".
A major error occurred in 2000 when the reverse die of aSacagawea dollar was combined with the obverse die of a state quarter on dollar-coin planchets to form what is known as a "mule". As of August 2019, only 19 ofthese specimens, produced on dollar planchets, are known to have escaped from the Mint.[44][45][46]
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.[47] Relatively more common are Kansas quarters bearing the motto "IN GOD WE RUST."[48]
The United States producesproof coinage in circulating base metal and, since 1992, in separately sold sets with the dimes, quarters, and half-dollars in silver. For the silver issues, the 1999 set is the most valuable, being the first year of the series and with a relatively small mintage, although prices have significantly decreased since the 50 State Quarters Program ended. 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. The public is cautioned to research prices before buying advertised state quarter year or proof sets.
In general, the program increased interest in quarter and general coin collecting.[49] Large numbers of advertisements, quarter products and quarter information were available during the years the program ran.Home Shopping Network,Franklin Mint, andLittleton Coin Company were among the most prominent in advertising 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.[4]
