This coin is a remarkable example of the U.S. Gold Dollar series, specifically minted in 1875 at the Philadelphia Mint. It is a one-dollar denomination, made of gold, which showcases the craftsmanship of late 19th-century American coinage. With a diameter of 15 mm and a weight of 1.67 grams, this coin is quite small yet historically significant. The Philadelphia Mint, denoted by the 'P' mint mark, produced a limited mintage of only 400 pieces for this year, making it relatively rare among collectors. As a representative of the Gold Dollar sub-type, it reflects both the economic conditions of its time and the broader context of U.S. coinage. The coin's intricate design and gold composition add to its allure and value, appealing to both numismatists and investors alike. Given its historical context, limited production, and intrinsic gold value, this 1875 Gold Dollar presents both a collectible opportunity and a glimpse into the monetary practices of post-Civil War America.
