The 50 State quarters, enacted December 1, 1997, was a series of circulating commemorative quarters released by the United States Mint. Minted from 1999 through 2008, they featured unique designs for each of the 50 US states on the reverse.
The 50 State Quarters Program was started to support a new generation of coin collectors, and it became the most successful numismatic
program in history, with roughly half of the US population collecting the
coins, either in a casual manner or as a serious pursuit.
Similarly another series - America the Beautiful quarters
(sometimes abbreviated ATB quarters) issued by the United States Mint, which
began in 2010 and lasted until 2021. A series of 56 25-cent pieces (quarters)
were issued.
This program was authorized by America’s Beautiful
National Parks Quarter Dollar Coin Act of 2008.
