In the realm of collectible coins, the three-dollar gold piece, often referred to as the "three-dollar gold coin" or "Princess," was minted in the United States from 1854 to 1889, though it is less common than other denominations. The Peace Dollar, which features a design symbolizing peace, was produced from 1921 to 1935, with the 1924 Peace Dollar being particularly sought after by collectors due to its high mintage and historical significance. Collectors value these coins for their artistic design and the stories they represent, making them prominent within American numismatic history.
