The term is notably associated with pieces struck in the late 19th century, including the 1884 So-Called Dollar, which commemorates the 1884 World's Fair in New Orleans. While not official currency, these items hold significance for collectors due to their historical context and unique designs, reflecting the culture and events of their time. The United States of America has produced various forms of these collectible pieces, appealing to numismatists and history enthusiasts alike.
