Modern Commemoratives are a category of collectible coins produced by the United States Mint that celebrate significant events, people, or themes in American history. These coins were authorized by Congress and minted starting in 1982, with many released annually. The 1990 one-dollar commemorative coins typically feature designs that honor specific anniversaries or milestones, often showcasing symbols of American heritage. Unlike circulating currency, these coins are often produced in limited quantities, making them popular among collectors.
