United States quarter-style coin featuring Dr. Vera Rubin

This item is a circular metallic coin that appears consistent with the United States Mint's American Women Quarters Program. The reverse side is visible, displaying a profile portrait of a woman looking through a telescope towards a starry sky, stylized to represent astronomical observations. The coin bears several verbatim inscriptions: 'UNITED STATES OF AMERICA', 'QUARTER DOLLAR', 'E PLURIBUS UNUM', 'DR. VERA RUBIN', and 'DARK MATTER'. The piece has a serrated or reeded edge and exhibits a bright, luster-filled metallic finish, typical of cupronickel clad or similar modern coinage compositions. While it bears all the markings of a 2025-series circulation coin, its status as legal tender cannot be verified from a photograph alone. The condition appears to be excellent with minimal visible wear, suggesting it may be in uncirculated or nearly uncirculated condition. The owner's note 'Good' is an unverified subjective assessment. Stylistically, this design is consistent with 21st-century commemorative circulation strikes produced by the U.S. Mint, specifically those issued to honor prominent American women. However, without a physical weight and metal analysis, the coin remains an unverified specimen.

Based on my visual analysis of the provided image, this item appears consistent with the reverse design of the 2025 Vera Rubin quarter from the American Women Quarters Program. I can see clear inscriptions such as 'DR. VERA RUBIN' and 'DARK MATTER' alongside a profile portrait, which suggests a modern commemorative circulation strike by the U.S. Mint. However, I cannot verify the metallic composition, weight, or specific mint mark from a photograph alone. While the owner characterizes the condition as 'Good,' the luster visible in the image suggests it may be in uncirculated or nearly uncirculated condition, though this would require an in-person examination to confirm. For an item of this type, the value is heavily dependent on the specific strike quality and presence of any errors. If this is a standard circulation coin, its value would primarily be its face value of $0.25. If it is an uncirculated specimen or a high-grade proof, it may reach the $1.00 to $5.00 range among collectors. General market demand for recent commemorative quarters is high for complete sets, but individual coins rarely command significant premiums unless they possess rare minting errors or are professionally graded in exceptionally high conditions (MS-67 or higher). To confirm the appraisal value, I would recommend a physical inspection to check for edge-to-surface wear and scientific testing to ensure it is not a plated replica or non-legal tender token. If the piece were found to be a reproduction or a struck copy rather than a government-issued coin, its commercial value would be negligible.
