Collectible coins, particularly those related to significant historical events, often hold substantial value among numismatists. The 1933 and 1934 Century of Progress Exposition in Chicago issued commemorative coins that celebrated scientific advancements and the centennial of the city. These coins, often made of materials like silver, feature distinctive designs reflecting the themes of innovation and progress. Their limited mintage and association with a notable event in U.S. history enhance their desirability among collectors.
