So-Called Dollars are a category of numismatic items that are not official U.S. currency but are issued to commemorate events, people, or places, often in the form of medals or tokens. The term originates from a collection compiled by Hibler and Kappen, which catalogs these pieces. The 1889 So-Called Dollar, especially, commemorates the 1889 opening of the Oklahoma Land Rush and features a design that reflects this historical event, leading to its popularity among collectors of American history and numismatics. These items are sought after for their unique designs and the stories they represent, marking milestones in American culture and history.
