National Numismatic Collection
The National Numismatic Collection is one of the world's largest collections of coins, paper currency, exonumia and related items. In total the collection contains over 1.6 million objects, including 450,000 coins, medals and decorations and 1.1 million pieces of paper money.
As of 2004, the exhibit housing the Collection was the last surviving exhibit from the Smithsonian Museum of American History's original 1964 arrangement. In late 2004, the exhibit was closed, and the Collection returned to the Smithsonian's vaults. Only a few dozen of the Collection's most notable specimens remain on display today.
