About this coinHistory

The 1849 proof is the first Liberty Head Double Eagle ever struck and the founding piece of the entire $20 gold series. Its production followed the Act of March 3, 1849, which authorized the new denomination in response to the flood of California Gold Rush bullion arriving at the Philadelphia Mint. Chief Engraver James B. Longacre prepared the dies through the autumn, and on December 22, 1849, Mint Director Robert M. Patterson reported that the working dies were complete and a specimen had been struck by hand on a medal press for Treasury approval. Numismatic literature has long held that two pieces were produced that day, although only one is accounted for today.

Longacre's obverse pairs a left-facing Liberty wearing a coronet inscribed LIBERTY with thirteen stars and the 1849 date, while the reverse carries a heraldic eagle, a shield, and an unbroken E PLURIBUS UNUM scroll, a configuration that would become the Type 1 No Motto design through 1866. The accounted-for specimen entered the Mint Cabinet directly from production and was transferred with that collection to the Smithsonian Institution, where it now resides in the National Numismatic Collection. The second piece is traditionally credited to Treasury Secretary William M. Meredith, with Walter Breen and others recording its passage into private hands and a possible mid-twentieth-century sighting through dealer William K. Nagy. Q. David Bowers has expressed skepticism that a second strike was ever produced, and no verified specimen has surfaced.

For collectors, the 1849 effectively does not trade. The Smithsonian piece has never been offered publicly and is treated as a permanent national holding, while the second example, if it exists, has been untraced for generations. Theoretical valuations of $15 million to $20 million or more reflect the coin's place alongside the 1933 Saint-Gaudens and the 1804 dollar in the top tier of American rarities, but those figures remain academic. Any future private offering would warrant exceptional documentary scrutiny given the long silence surrounding the Meredith piece. For broader background on the design family this pattern launched, see the Liberty Head Double Eagle series history.
