The first U.S. Mint was started by an act of Congress in Philadelphia in 1792. Through the years, the mint has relocated several times. The current facility, the fourth U.S. Mint in Philadelphia, has been in use since 1969. It can produce 1 million coins in 30 minutes; while the first mint would take about three years to produce the same number of coins.
Free tours are available from 9:30 a.m. to 4:30 p.m. Monday through Friday.
