The John Quincy Adams one-dollar coin was minted by the U.S. Mint between 2008 and 2011 as a part of a presidential heritage collection. The Mint ceased production of these coins except for collector proofs in 2011 because the supply of one-dollar coins exceeded public demand. The John Quincy Adams coin was released as sixth in the series.
The John Quincy Adams coin features a bust of the president on one side of the coin with his name on the top of it and the years in office underneath. Around the edges of the coin are the year of mint, 2008, and the motto of the United States. The reverse side of the coin depicts the Statue of Liberty with the denomination and the country's name.
While John Quincy Adams was president, he passed legislation that required the Mint to remain indefinitely in Philadelphia. He also created a standard weight requirement for coins produced by the Mint and developed a testing program to determine the purity of the bullion that was acquired by the Mint for pressing into coins. President John Quincy Adams made sure that the new program was funded and arranged for clerks to be employed at the Mint.
