Whether you have plenty of it or you don't have nearly enough, money is something that everyone is interested in. Get a different view of currency when you take a tour of the Money Museum at the Federal Reserve Bank of Cleveland. Check out thirty exhibits about the history and power of money. One of the many highlights include a 23-foot-tall money tree that is located right across from the museum's entrance. While the majority of the tour is self-guided, the admission is free.
