The collection is part of the Smithsonian Institution's National Museum of American History.
The National Numismatic Collection comprises approximately 1.6 million objects and is one of the world's largest and most diverse collections of coins, paper currency, medals, commodity currencies, financial instruments, exonumia, and related items.
In addition, it includes collections donated by individual collectors and private institutions, such as the collection of the Chase Manhattan Bank Money Museum.
In late 2004, the exhibit was closed, and the objects were returned to the Smithsonian's vaults.
In 2015, the museum opened a new permanent Gallery of Numismatics with an exhibition titled The Value of Money.
