As the Mint's Chief Engraver from 1965 to 1981, Gasparro also created designs for the reverse of the Kennedy half dollar, for which he took painstaking attention to the details of the design of the Seal of the President of the United States, making the words "E pluribus unum" more prominent. Other designs by Gasparro included medals for Winston Churchill, Albert Gallatin, Douglas MacArthur and Sam Rayburn, along with the presidential medals for all Presidents from Lyndon B. Johnson to Ronald Reagan and numerous foreign coins produced by the Mint. One of his best known works was the obverse of the Congressional gold medal for John Wayne, widely bought by the public in bronze.
