So-Called Dollars are a type of numismatic item that refers to medallic pieces issued to commemorate events or places, rather than as legal tender. The term originates from a series of medals that were issued in the United States during the mid-19th century, particularly by Hibler and Kappen. The 1984 So-Called Dollar, often associated with the 1984 Summer Olympics in Los Angeles, features unique designs and is sought after by collectors for its historical significance and artistic merit. These items are classified with distinct catalog numbers for reference among collectors.
