The coin in question is a 1924 Standing Liberty Quarter, a notable piece of American numismatic history. Minted in Denver, as indicated by its "D" mint mark, this quarter is part of a series known for its artistic design and historical significance. Struck from 90% silver and weighing 6.25 grams, it has a diameter of 24.3 millimeters, which is standard for U.S. quarters. The Standing Liberty Quarter was first introduced in 1916 and features a design by sculptor Hermon Atkins MacNeil. The obverse depicts Lady Liberty standing confidently, holding a shield and a raised lamp symbolizing hope and guidance. The reverse features an eagle in flight, a striking representation of American freedom and strength. In 1924, only 3,112,000 of these quarters were minted, making it a relatively common date in terms of mintage but still sought after by collectors today. Its composition of silver not only gives it intrinsic value but also adds to its appeal among numismatists. Overall, this 1924 Standing Liberty Quarter is a remarkable piece of American currency, combining beautiful artistry with historical significance, representing both the era in which it was minted and the enduring legacy of U.S. coinage.
