This coin is a 2019 American Innovation Dollar, struck in the United States. As part of the American Innovation series, it celebrates various aspects of American ingenuity and achievements. This particular coin is a proof version, indicating that it was produced with a higher level of detail and finish compared to standard coins, making it especially appealing to collectors. Notably, this coin is distinguished by the absence of a mint mark, which may suggest it was produced at an unknown mint or as part of a special release. The coin's diameter, height, width, and weight have not been specified, which is unusual, as these measurements typically help define a coin's physical characteristics. Additionally, it is important to note that the mintage has been listed as '0', which may imply that either no coins were produced or the production details are unclear. This could significantly affect its collectible value, as limited or unique pieces often have higher demand among collectors. Elevated by its $1 denomination, this coin represents not only a denomination of currency but also a piece of commemorative art reflecting the innovation that has shaped the United States. Due to its proof status and potential rarity, it may hold considerable value for numismatists and those who appreciate American heritage.
