What us mint created the first coins?

The first US Mint was located in Philadelphia. It produced its first general-circulation coins (large cents and half cents) in 1793.

Philadelphia was the only US Mint until 1838 when branch mints were opened in Charlotte and Dahlonega GA to mint coins from the gold deposits found there. Other mints followed, and today there are 4 active ones. Philadelphia and Denver make circulation coins, San Francisco makes proof coins for collectors, and West Point makes commemorative and bullion investment coins.
