The coin in question is a stunning example of the Three Dollar Gold series minted in 1870 at the San Francisco Mint. Designed by the renowned engraver James Barton Longacre, this coin showcases exquisite craftsmanship typical of its era. It features a denomination of $3, highlighting its unique status within the American coinage system. This particular example is made from a gold alloy containing 90% gold and 10% copper, giving it not only beautiful luster but also intrinsic value due to its gold content. Measuring 20.5 mm in diameter, it has a reeded edge that adds to its distinct aesthetic appeal. Remarkably, this specific coin is part of a very limited mintage, with only one known to exist, making it exceptionally rare and highly sought after by collectors and numismatists alike. The coin bears no mintmark, which is consistent with its production at the San Francisco Mint during that year. Overall, the 1870 Three Dollar Gold coin represents a significant piece of American history, combining artistry, rarity, and the enduring allure of gold coinage. Its exceptional condition contributes to its value as both a collector's item and a historical artifact from the United States of America.
