The 1886 So-Called Dollar is a commemorative piece issued in the United States, capturing a significant event or sentiment of its time. These tokens, often associated with the Centennial Exposition in Philadelphia, were not official currency but were created to celebrate important national milestones. The term "So-Called Dollar" refers to coins or tokens that are dollar-sized but were not minted as legal tender by the U.S. government. Collectors prize these for their historical context and unique designs, making them a notable segment in the broader category of American numismatics.
