So-Called Dollars refer to a category of commemorative medals and tokens issued in the United States, particularly between the mid-19th and early 20th centuries. These items often featured a dollar denomination but were not official currency. Many were created to celebrate significant events or figures in American history. The 1853 So-Called Dollar is particularly notable for its association with the 1853 International Exposition in New York City, reflecting the era's cultural and economic aspirations. Collectors value these pieces for their historical significance and artistic designs.
