"Half dollar sized" refers to an object that has a diameter similar to that of a U.S. half dollar coin, which measures approximately 1.205 inches (30.61 mm). This term is often used to provide a visual reference for the size of various items, making it easier for people to understand how large or small something is in comparison to a familiar object. The U.S. half dollar coin features the image of John F. Kennedy on one side and the Great Seal of the United States on the other. It is commonly used in everyday transactions, though it is less frequently seen in circulation compared to smaller denominations like the quarter or dime.
