Since 1999, the US Mint has released 5 quarters every year. The 50 State Quarters Program lasted 10 years and honored each of the nation’s states in the order that they ratified the Constitution or were admitted into the Union. Each quarter was produced for about 10 weeks and will never be produced again. The 50 State Quarter Program became the most successful numismatic program in history. There were 35,001,138,000 State Quarters issued between 1999-2008. According to the US Mint, 147 million people collect the 50 State Quarters.
Because of the success of the 50 State Quarter program, the US Mint launched the America The Beautiful (ATB) Quarter program in 2010 and continued the release of 5 quarters per year. Each ATB quarter depicts a national park or national site from each state and is scheduled to continue until at least 2021.
