Kennedy, is still remembered on the annually produced half dollar struck in his honor since 1964.
Kennedy half dollar : The shot heard around the world in 1963, a bullet from an assassin's weapon that ended the life of U.S. Stanton and Bill Fivaz’s current edition of the Cherrypickers’ Guide to Rare Die Varieties of United States Coins. Though the variety was discovered in the 1980s, relatively few have surfaced. The design element is likely missing because the dies were ground down at the U.S. On some 1972-D half dollars, these initials are missing.
The FG refers to the initials of designer Frank Gasparro, normally found on the reverse below the right leg of the eagle. The 1972-D Kennedy half dollar “No FG” reverse variety has grown in popularity in recent years and examples can still be cherrypicked by sharp-eyed collectors.
