Coinage Act of 1792

The Coinage Act or the Mint Act, passed by the United States Congress on April 2, 1792, created the United States dollar as the country's standard unit of money, established the United States Mint, and regulated the coinage of the United States. The long title of the legislation is An act establishing a mint, and regulating the Coins of the United States. This act established the silver dollar as the unit of money in the United States, declared it to be lawful tender, and created a decimal system for U.S. currency.

By the Act, the Mint was to be situated at the seat of government of the United States. The five original officers of the U.S. Mint were a Director, an Assayer, a Chief Coiner, an Engraver, and a Treasurer (not the same as the Secretary of the Treasury). The Act allowed that one person could perform the functions of Chief Coiner and Engraver. The Assayer, Chief Coiner and Treasurer were required to post a $10,000 bond with the Secretary of the Treasury.

The Act pegged the newly created United States dollar to the value of the widely used Spanish silver dollar, saying it was to have "the value of a Spanish milled dollar as the same is now current".

Although some of the provisions in the 1792 Coinage Act were adjusted as time went by, the majority of the rules specified in this Act remained in effect for many decades. Essentially, it provided the basic framework on which all subsequent coinage production was based. While the first draft of the Act stipulated that all coins would employ a portrait of the president on the obverse, the final version called for an image emblematic of liberty as well as the word "liberty". The Act also authorized construction of a mint building in Philadelphia, the nation's capital. This was the first federal building erected under the United States Constitution. Mint director David Rittenhouse laid the building's cornerstone on July 31.
