Collectible coins encompass a diverse range of numismatic items, including commemorative and limited-edition pieces, often minted to honor specific events or anniversaries. One significant type is the coins produced for world fairs and expositions, such as those minted for the 1933 and 1934 Century of Progress Exposition in Chicago. These coins typically feature distinctive designs reflecting the themes of innovation and progress celebrated at these events. The 1933 and 1934 coins are particularly sought after by collectors due to their historical context and the unique artistry associated with the century's fairs.
