Commemorative coins are special issues that celebrate significant events, persons, or anniversaries in history. In the United States, the 50-cent commemorative coin from 1947 honors the 250th anniversary of the founding of the city of Philadelphia and features a design by engraver John R. Sinnock. These coins are produced in limited quantities and hold collectible value, often sought after by numismatists for their historical significance and unique designs.
