Would you like to actually watch money being made? See early coins and learn the story behind our nation's currency? Visit the Philadelphia Mint. Stroll through the visitor's gallery and view the modern coin-making process: huge machines that work 24 hours a day, five days a week. Then see the original coining press used in 1792. Open for public tours Monday through Friday from 9 am to 4:30 pm. All tours are free and self-guided.
