Celebrating the 125th Anniversary of the Lightbulb
Thomas Edison’s 1879 public demonstration of his incandescent lamp did not mark the first use of electric light, but it represented a major breakthrough in creating a practical, reliable system of electric lighting suitable for everyday use. Earlier experiments, including Humphry Davy’s 1802 demonstration of an electric arc lamp, proved that electricity could produce light but were limited to laboratory or industrial settings.
Inventors such as Warren de la Rue, James Bowman Lindsay, Joseph Swan, and Woodward & Evans made important advances, but it was Edison who successfully combined a long-lasting carbonized bamboo filament with a vacuum-sealed bulb and a complete electrical distribution system, enabling widespread adoption in homes and businesses. Its smaller size and steady light made it more convenient than bulky arc lamps, opening the door to widespread electrification in homes and businesses. Lewis Latimer played a crucial role in this development through his improvements to carbon filament manufacturing and his technical contributions to the electric lighting industry.
The 125th Anniversary of that invention was approaching in 2004, and the United States Congress saw fit to honor Edison and his life-changing invention with the 2004 Thomas Alva Edison Commemorative Silver Dollar.
Proceeds from each coin are divided equally among eight institutions that safeguard Thomas Edison’s legacy: the Port Huron Museum of Arts and History, the Edison Birthplace Association, the National Park Service, the Edison Plaza Museum, the Edison Winter Home and Museum, the Edison Institute, the Edison Memorial Tower, and the Hall of Electrical History. Each organization will use its share to repair, refurbish, and maintain its facilities.
Coin Design Details
The obverse of this coin was designed by Donna Weaver, who had previously designed or partially designed several other commemorative coins in the early 2000s, including the 2004 Lewis & Clark Bicentennial Silver Dollar, the 2005 Chief Justice John Marshall Silver Dollar, and the 2007 Jamestown 400th Anniversary Silver Dollar. The obverse of this coin depicts a half-length portrait of Edison, holding a lightbulb in his hand, facing the viewer. Above him is the word “LIBERTY,” and to the right is “THOMAS ALVA EDISON.” To the left is “IN GOD WE TRUST,” and again to the lower right is the date “2004.”
The reverse was designed by John Mercanti and features a rendition of Edison’s first lightbulb, with light rays emanating from it. The upper periphery has “125TH ANNIVERSARY OF THE LIGHT BULB,” and on either side are the dates “1879” and “2004.” Below those dates are “UNITED STATES OF AMERICA,” the denomination “ONE DOLLAR,” and on the bottom periphery “E PLURIBUS UNUM.”
The 2004 Thomas Alva Edison Commemorative Silver Dollar was struck in uncirculated and proof at the Philadelphia Mint. Congress authorized a maximum of 500,000 coins, but only 92,510 uncirculated and 211,055 proof coins were sold.
The coins were sold individually and in a 2-coin set, and the uncirculated silver dollar was packaged in a Collector’s Case that included a functioning light bulb resembling one of Edison’s first bulbs. Add this coin to your collection and explore other U.S. classic silver commemorative coins.
