The permanent exhibit “Money: A History” has the broadest appeal across age groups and includes a beaver pelt (a form of Colonial currency), a 60-pound, solid gold bar and a vintage $10,000 bill (they stopped being produced in 1969). Today, the highest denomination printed by the Treasury is the measly $100 note.

For kids curious about what all the symbols and squiggles on our currency mean, a freestanding interactive station offers a 360-degree virtual view of the dollar bill, and points out various security measures. Next to it, a machine allows visitors to confirm their own bills’ authenticity. On the flip side, youngsters can put their hands on seven vintage American coins from the 19th and 20th centuries (no more rooting through Dad’s old collection), as well as a Roman coin depicting the profile of Emperor Constantine I.
