This coin is a part of the 90% silver quarters produced by the U.S. Mint prior to 1965, making it a sought-after collectible among numismatists, especially in higher grades due to its silver content and historical significance. The 1951-S variant is particularly noted for its lower mintage compared to other years, enhancing its appeal to collectors.
