肯尼迪半美元
Frank Gasparro's reverse design of the Kennedy half dollar was also influenced by the experience he gained from designing the President John. F. Kennedy appreciation medal. In 1962, President Kennedy had three hundred appreciation medals struck by the United States Mint in Philadelphia that were later presented during his June 23, 1963 through July 2, 1963 trip to the nations of Federal Republic of Germany, Germany (West Berlin), Ireland, United Kingdom, Italy, and the Vatican City State. The reverse design of the Kennedy appreciation medal depicts a larger and more detailed Presidential Seal than the one he designed on the Mint's Presidential series (Bureau of the Mint Presidential series stock medal #135 known as the John F. Kennedy Presidential inauguration medal). Gasparro's placement of his initials FG is also similarly located (under the right leg of the eagle) on both the Kennedy appreciation medal and Kennedy half dollar.
