All components are safe for your currency and inert. 50 State Quarters™ Program's background: The United States Mint's 50 State Quarters Program, which was introduced in 1999, was a ten-year project that celebrated every state in the country in the order that they ratified the Constitution or were brought into the Union. The production of each quarter, which lasted for around 10 weeks, has ended, and won't be repeated. The reverse (tails) of the quarters includes state designs, while the obverse design features the well-known portrait of George Washington. However, the phrases "United States of America," "Quarter Dollar," "Liberty," and "In God We Trust" all appear on the obverse to accommodate state designs on the reverse. What are the D.C. and U.S. Territories Quarters about? The District of Columbia and five U.S. territories—the Commonwealth of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands—were each given a quarter-dollar coin by the United States Mint in 2009. In 2009, the coins were released in the specified sequence at equal intervals. These coins will be released into circulation in sufficient numbers to satisfy both the country's commercial and collector interests. The Secretary also has the power to mint and issue proof and uncirculated coins, as well as versions of each coin that are 90% silver.
