Classic commemorative coins were issued by the United States Mint from 1892 to 1954 to celebrate significant events, people, and places. The 1904 Classic Commemorative One Dollar coin, minted in Philadelphia, was produced to honor the Louisiana Purchase Exposition held in St. Louis. These coins are notable for their artistic designs and limited mintage, which contribute to their collectibility and historical significance among numismatists.
