The Collection

The National Numismatic Collection is comprised of approximately 1.6 million objects and is thought to be the largest money collection in the world. Its diverse holdings represent every inhabited continent and span more than three millennia, ranging from Mesopotamian cuneiform tablets to 21st-century credit card readers.

The collection has grown from a few thousand objects in the mid-19th century to its present size through donations from public institutions and private collections.

The National Numismatic Collection is unrivaled in its holdings of American material. It is the U.S. monetary system's collection of record and includes the extraordinary collections of the U.S. Mint, Treasury, and Bureau of Engraving and Printing.

Other notable collections include:

  • The Chase Manhattan Collection
    Approximately 24,000 American and international banknotes, coins, banking materials (including a rare collection of U.S. presidents’ personal checks), and alternative and commodity currencies
  • The Confederate Currency Collection, also known as "The Richmond Hoard”
    Approximately 600,000 Confederate banknotes
  • The Josiah K. Lilly Jr. Collection
    6,125 American and international gold coins and bars, including an almost complete collection of U.S. gold coins
  • The Paul A. Straub Collection
    About 5,600 European gold and silver coins ranging from the 14th to 20th centuries
  • The Grand Duke Georgii Mikhailovich Collection

Ancient Greek and Roman Coins

The National Numismatic Collection holds approximately 26,900 Greek and Roman coins and has good representation in all areas of ancient coinage.  A group of scholars recently carried out an assessment that revealed some exceptional strengths of the collection, including world-class holdings of eastern Roman provincial and civic coin issues and a number of older hoards. A narrative overview of the assessment is available here and a more detailed listing of the NNC’s classical coin holdings is available here.


Accessing the collection online

A small portion of the National Numismatic Collection is available online through NMAH's online catalog. The National Numismatic Collection is currently working to develop digitization initiatives in order to make the collection more accessible to the public.


Recent digitization initiatives

Howard F. Bowker East Asian Coin Project

The National Numismatic Collection is currently digitizing its East Asian coin collection thanks to a generous donation from the Howard F. Bowker Family and Michael Chou. A dedicated member of staff is cataloging and photographing approximately 8,500 coins and related monetary objects spanning nearly three thousand years of East Asian history.  The collection will be publicly accessible via our collections catalog in 2018.

John Adams Comitia Americana Medals Project

The National Numismatic Collection recently completed the digitization of its Comitia Americana medals thanks to a generous donation from John Adams. A dedicated member of staff cataloged and facilitated the photography of 119 medals struck between 1776 and the late 19th century. This group of historic medals represent a newly independent United States engaging with the international community through numismatic art.

Bureau of Engraving and Printing Rapid Capture

In October 2014 the National Numismatic Collection initiated an innovative “Rapid Capture” digitization project, pioneering one of the first projects of its kind at the Smithsonian. The goal of the project was to digitize about 250,000 proof sheets from the Bureau of Engraving and Printing (BEP) collection, consisting of over a quarter-million unique sheets used to print banknotes and tax stamps from 1863 to the early 20th century. These proof sheets were kept by the BEP as a collection of record for the currency issued during this time and were transferred to the National Numismatic Collection between the 1960s and 1980s.

The project involved a conveyer belt system with a custom-designed 80 megapixel imaging system to digitize the objects as efficiently as possible. This innovative process was incredibly effective when compared to the old method of employing a flatbed scanner. The digitization team processed nearly 3,500 sheets every day at a cost of less than a dollar per sheet in just four and a half months!

Another component of this project was the integration of the Smithsonian’s Transcription Center. Through this online platform, members of the public are able to log on, see our objects, and assist us with cataloging them by filling in predetermined information fields. Their work has allowed us to catalog objects quickly and efficiently.

At the completion of the project, the team was able to digitize 274,340 currency proof sheets from our collection. The sheets are still going through the transcription process.

The National Numismatic Collection is constantly looking for new and innovative ways to make our collections accessible, furthering the Smithsonian Institution’s mission of sharing our valuable resources with the world.


Recent Rehousing Initiatives

Rehousing the International Paper Money Collection

The NNC recently rehoused its international banknote collection thanks to a generous donation from Dr. and Mrs. Andrew Shiva. Two dedicated members of staff moved all the notes from degrading plastic sleeves, into new, archival quality folders for their long-term preservation. The collection consists of more than 80,000 individual pieces of paper money, dating from the late 18th century to present day and representing dozens of countries around the world. While working through the collection, the team also revealed its potential as a resource for historical research.
