In 1834, Congress made a dollar worth slightly less, thus lightening U.S. gold and silver coins (known collectively as specie), making them uneconomical to export, and they were seen more often in commerce within the U.S. With this greater circulation, Congress re-examined the existing statutes relating to the Mint, and found many provisions to be obsolete. It enacted the Mint Act of 1837, a thorough revision of the statutes relating to the Mint. New provisions included the establishment of a bullion fund, allowing depositors to be paid without waiting for their metal to go through the coining process. The ratio of value between equivalent weights of gold and silver was adjusted slightly, allowing coins of both metals to circulate within the U.S.
