Three Dollar gold coins, also known as "Princess" coins, were minted by the United States from 1854 to 1889. The coins feature a design that includes a portrait of Lady Liberty on the obverse and an eagle on the reverse. The 1889 Three Dollar gold coin is particularly noteworthy due to its limited mintage and is sought after by collectors. These coins contain 0.0900 troy ounces of gold and are considered a significant part of American numismatic history.
