(n.)
In heraldry, a mullet refers to a star with straight rays, such as the star used on the American flag. While different heraldic systems have different definitions, a mullet can be assumed to have five points unless otherwise specified. Early 20th-century coin promoter and American Numismatic Association (ANA) President Farran Zerbe lobbied the United States Mint to use only the mullet to represent stars on U.S. coin designs.
