-History of the Kennedy Half Dollar-
The Kennedy half dollar replaced the Franklin half dollar within a year of the assassination of President John F. Kennedy. In fact, Gilroy Roberts, the former chief engraver of the mint, and Frank Gasparro, the current chief engraver at the time, designed the coin a mere five days after Kennedy's death—though the profile of Kennedy was the same one Roberts had used for Kennedy's inaugural medal two years earlier.
Ironically, the new Kennedy design caused the slow disappearance of the half-dollar as a regular mainstream circulating coin, through a series of unrelated events. First, collectors and even ordinary citizens hoarded the coins of 1964, due to the "new" design and because of sentiment for the late President Kennedy. In 1965 silver was eliminated from other coin denominations (dimes and quarters became copper-nickel clad), but silver remained in the half-dollar. The older Franklin halves of 90% silver were quickly removed from circulation by collectors and hoarders, and since the public now hoarded silver coins, most of the 90% silver 1964s, as well as the 40% silver composition 1965-1970 halves, saw little circulation as well. By time the Kennedy half dollar became regular copper-nickel clad in 1971, many banks and merchants were already used to no longer stocking and using the denomination as they were prior to 1964. The half dollar has always circulated to some extent, but has not at the level of circulation it had before 1964. Given the facts that the cash drawers of most merchants do not contain a place for quantities of half dollars, that most vending machines do not accept them, and that the dollar coin is smaller and is the subject of a push for acceptance, the half is likely to retain its limited circulation status.
When the 1964 proof coins were first minted, the "I" in "LIBERTY" had a truncated lower-left serif, and the hair above Kennedy’s ear was heavily incised. After approximately 120,000 coins were produced, the dies were revised and the hair smoothed slightly. Jacqueline Kennedy was thought to have disliked the earlier, "accented hair" version (as it came to be known), although the lower relief design might have also have been introduced to facilitate production.[1] Coins produced from the first die typically sell for about four times those from the later version. However, since a substantial number of the earlier coins seem to have been poorly struck, top quality specimens can fetch even higher prices.
After the 1964 coin's introduction (around the height of the cold war), the Denver Mint received a number of complaints that the base of Kennedy’s neck bore the hammer and sickle symbol. However, closer examination will reveal that the mark is actually a script form of the initials "GR": Gilroy Roberts’ monogram.[2]
In 1975 and 1976, the bicentennial half dollar was minted showing Independence Hall on the reverse. All of the bicentennial halves are dated "1776–1976." While the special half sparked some interest in the public, when the half returned to its regular design in 1977, it continued its decline in use and mintage. By 2002, the coins were no longer minted for commercial use, but only in special mint rolls, mint sets, and proof sets for collectors.
