How did the first US coin program start?

Before the Coinage Act of 1792, foreign coins were used for trade and commerce in the United States. The new republic, under the 1972 Coin Act, established the United States Mint. Thus, the production of the new US dollar coins standardized the nation's monetary unit. Where are US coins made? The US Mint has several branches scattered across the country. Each mint has its own mintmark (symbol that indicates where the coins were made). The main mint is the Philadelphia Mint (with a P mintmark). Other mint branches are located in Denver (D), San Francisco (S), and West Point (W). At present, the non-operating mints are in Carson City (CC), Charlotte (C), New Orleans (O), and Dahlonega (D). The mintmarks are often found near the mint year.  more
