On June 2, 2025, the United States Mint began shipping the latest addition to its American Women Quarters Program: a coin honoring Dr. Vera Rubin, the pioneering astronomer whose work provided compelling evidence for the existence of dark matter. This release marks the third coin in the 2025 series, celebrating Rubin’s transformative contributions to science and her role as a trailblazer for women in astronomy.
Celebrating a Scientific Luminary
Dr. Vera Rubin’s groundbreaking research in the 1970s revolutionized our understanding of the universe. By meticulously studying the rotation curves of galaxies, she observed that stars at the outer edges rotated at speeds that couldn’t be explained by visible matter alone. This discrepancy pointed to the presence of an unseen mass—what we now refer to as dark matter—constituting over 80% of the universe’s mass.astronoo.com
Rubin’s findings not only confirmed earlier hypotheses about dark matter but also opened new avenues in astrophysics and cosmology. Her work laid the foundation for subsequent research into the universe’s structure and composition, influencing generations of scientists.United States Mint
A Coin Reflecting Cosmic Contributions
The reverse side of the new quarter features a profile of Dr. Rubin gazing upward, surrounded by a spiral galaxy and other celestial bodies. Inscriptions include “DR. VERA RUBIN,” “QUARTER DOLLAR,” “E PLURIBUS UNUM,” “UNITED STATES OF AMERICA,” and “DARK MATTER.” This design symbolizes Rubin’s profound impact on our cosmic understanding and her dedication to unveiling the universe’s mysteries.
Christina Hess, an Artistic Infusion Program designer, crafted the coin’s imagery, which was sculpted by Mint Medallic Artist John P. McGraw. The coin is minted at the Philadelphia and Denver facilities, ensuring widespread circulation.

The American Women Quarters Program
Authorized by the Circulating Collectible Coin Redesign Act of 2020, the American Women Quarters Program is a four-year initiative running from 2022 through 2025. Each year, the program releases five new reverse designs, honoring women who have made significant contributions to the United States in fields such as suffrage, civil rights, government, humanities, science, and the arts.
Dr. Vera Rubin’s inclusion in this program underscores her pivotal role in science and her enduring legacy as a champion for women in STEM.
A Legacy Beyond the Stars
Born on July 23, 1928, in Philadelphia, Pennsylvania, Vera Rubin developed an early fascination with the cosmos. Despite facing gender-based barriers in her academic pursuits, she earned degrees from Vassar College, Cornell University, and Georgetown University. Rubin’s perseverance led her to become the first woman permitted to observe at the Palomar Observatory in 1965.Encyclopedia Britannica+1Wikipedia+1Wikipedia+1Teen Vogue+1
Throughout her career, Rubin advocated for the inclusion of women in science, mentoring countless aspiring female astronomers. Her accolades include the National Medal of Science and the Gold Medal of the Royal Astronomical Society. In 2020, the Vera C. Rubin Observatory in Chile was named in her honor, continuing her mission to explore the universe’s hidden facets.Wikipedia+1WIRED+1
Dr. Rubin passed away on December 25, 2016, leaving behind a legacy that continues to inspire. The release of this commemorative quarter serves as a tribute to her monumental contributions and her unwavering commitment to scientific discovery.Encyclopedia Britannica+2Teen Vogue+2Wikipedia+2
