National Numismatic Collection - Introduction

The National Numismatic Collection (NNC) of the Smithsonian Institution is one of the largest numismatic collections in the world and the largest in North America. With over 1.6 millioin objects, the NNC contains many great rarities in coins and currency, from the earliest coins created 2,700 years ago up to the latest innovations in electronic monetary exchange, as well as fascinating objects such as beads, wampum, dentalia, and other commodities once used as money.
The collection emphasizes the development of money and medals in the United States. The core of the U.S. collection, consisting of more than 18,000 items, including coins of great rarity, came to the Smithsonian in 1923 from the United States Mint. Exceptional rarities include the Brasher half doubloon, the 1849 double eagle (first of the gold 20 dollar pieces), and two 1877 fifty dollar patterns. Other rarities are include the 1913 Liberty head nickel as well as all three types of the 1804 dollar, and two of three known examples of the world's most valuable coin, the 1933 double eagle, the third of which recently sold for 7.6 million dollars.

Below you will find a selection of over 350 objects from the collection. We are working to expand and improve online access to additional objects in the near future, so stay tuned.

Clark, Gruber & Co., 20 Dollars, 1860
- Description
- A decade or so after the California Gold Rush began in the late 1840s, gold was discovered on the South Platte River, near the future city of Denver. As with the earlier strike, this one occasioned disputes over the value and purity of gold dust, as well as great difficulties in getting the precious metal all the way to Philadelphia to be coined there, and shipped back again.
- Matters would be greatly simplified if a coiner, either private or public, could set up shop near the gold fields. A good candidate existed-Clark, Gruber & Co. Up to now, the firm had acted as brokers, bankers, and assayers. But if a coinage was wanted, Austin and Milton Clark and Emmanuel Gruber were up to the challenge and had the resources to do it right.
- Milton Clark went back East to get the necessary machinery, three lots were purchased in Denver, and a two-story brick building soon went up on the property. Trial strikes of the four denominations to be coined ($2.50, $5, $10, and $20) were ready for inspection by mid-July 1860, and formal coinage began about a week after that.
- One of the firm's most famous products showed a marvelous, if unrealistic, image of Pikes Peak, beneath which Denver-and the Clark, Gruber enterprise-sat. The facility remained in operation through 1862, although all of its coins were dated 1860 and 1861. It was elbowed out of the coining business in April 1863. It turned first into a federal assay office, then 43 years later, into another branch of the United States Mint.

United States, Five Dollars, 1860 (Colorado-Clark, Gruber & Co)
- Description
- Produced by the Clark, Gruber & Company's mint, Denver, Colorado. Obverse: Head of Liberty facing left, date below, as on regular federal issues. Reverse: Eagle, denomination below. For its half eagles, Clark, Gruber & Co. abandoned the Pikes Peak motif that it used on its larger coins. The company brought the designs for the five dollar pieces into conscious imitation of regular United States coins.
