| Reverse description | Left-facing bust portrait of astronomer Dr. Vera Rubin set against a dynamic cosmic background featuring sweeping galactic spiral arms, stars, and curved bands evoking the invisible gravitational influence of dark matter. The subject's name DR. VERA RUBIN arcs prominently across the lower field in large lettering, with QUARTER DOLLAR curving along the upper legend and UNITED STATES OF AMERICA along the left periphery. The motto E PLURIBUS UNUM appears in the central field, and DARK MATTER is inscribed along the lower border; the engravers' initials CLH and JPM are present in the field. |

| Additional information |
Vera Rubin spent decades fighting for telescope time that male colleagues received as a matter of course, and her observational work on galactic rotation curves in the 1970s — conducted largely at Kitt Peak and Lowell Observatory — produced the most compelling early evidence for dark matter. The astronomical establishment was slow to credit it. She was nominated for the Nobel Prize repeatedly and never received one; she died in 2016 before the committee acted.
This .999 silver version was struck for the collector market alongside the standard clad circulation issue, part of the American Women Quarters Program authorized by Congress in 2021.
