The coin in question is a 2019 Modern Commemorative Gold coin, specifically a $5 denomination issued by the United States of America. This particular coin is characterized by its Proof production type, which means it was struck using a specialized process that results in a high-quality, mirror-like finish and sharp details. It features a diameter of 21.6 mm and is composed of 90% gold and 10% copper, which enhances its durability while maintaining the aesthetic appeal associated with gold coins. While this coin does not have a designated mint mark, it was struck with a total mintage of zero, implying it may be a special issue or perhaps not released to the public. Given its status as a modern commemorative coin, it likely celebrates a significant event, person, or theme reflective of American history or culture. The absence of specific details like the designer and mint type suggests a focus on its commemorative significance rather than its manufacturing origin. Overall, this coin represents not only a piece of currency but also a collectible item that embodies artistry and historical value, making it appealing to both numismatists and those interested in commemorative artifacts.
