The Half Dollar of the United States, sometimes known as the fifty-cent piece, has been produced nearly every year since the inception of the United States Mint in 1794. The only U.S. coin that has been minted more consistently is the cent.
Half dollar coins are commonly used in casinos. In particular, rolls of half dollars are kept on hand in cardrooms in the United States for games requiring 50-cent antes or bring-in bets, or where the house collects a rake in increments of 50 cents (usually in low-limit seven-card stud and its variants).
The half dollar's circulation, aside from use in some casinos and movie theaters, has declined significantly. This is primarily due to a confluence of two events: the silver crisis of 1963, and the assassination of U.S. President John F. Kennedy. The value of silver had risen by 1962-63 to the point that it became worthwhile to melt down U.S. coins for their bullion value. U.S. Silver coins (those of ten cent value and above, which contained 90% silver through 1964) began to disappear from circulation, leading the United States to change to layered composition coins made of a copper core laminated between two cupro-nickel outer faces for the 1965 - present coinage years. The Kennedy half-dollar design, however, continued to be minted in a 40% silver-clad composition from 19651970.
Initially the Kennedy halves were hoarded for sentimental reasons and because they were recognized as the only precious metal U.S. coin remaining in circulation. By the time mintage figures could match normal demand and the coin's composition was changed to match the rest of the (non-silver) coinage in 1971, both businesses and the public had adapted to a world in which the half dollar did not generally circulate. Other uses had been found for the half-dollar section of the cash drawer. People had gotten used to depending on quarters as the major component of change.
Most coins enter circulation through the change drawers of businesses. Hardly any businesses stock their change drawers with half dollars or dollar coins, and many banks do not stock these coins and/or hand them out as normal business practice, so the coins do not see much circulation. The fact that virtually no vending machines in the United States accept half dollars does not help its circulation either.

Obverse: Bust of Lady Liberty
Reverse: A bald eagle
Draped Bust (1796-1807)
Obverse: Lady Liberty
Reverse: A bald eagle
"Draped Bust" was the name given to a design of United States coins. It appeared on all regular-issue copper and silver United States coinage from 1795-1808. The denominations that featured the Draped Bust design included the half cent (1800-1808), large cent (1796-1807), half dime (1796-1805), dime (1796-1807), quarter (1796, 1804-1807), half dollar (1796-1807) and silver dollar (1795-1804). Gold coins did not carry this design.
Capped Bust (1807-1839)
Obverse: Lady Liberty
Reverse: A bald eagle
Seated Liberty Half Dollars (1839-1891)
Obverse: Lady Liberty seated holding the Union Shield
Reverse: A bald eagle
The "Seated Liberty" designs appeared on most regular-issue silver United States coinage during the mid- and late-nineteenth century, from 1836 through 1891. The denominations which featured the Seated Liberty design included the half dime, the dime, the quarter, the half dollar, and the silver dollar. Another coin that appeared exclusively in the Seated Liberty design was the twenty cent piece. This coin was produced from 1875 to 1878, and was discontinued because it looked very similar to the quarter. Seated Liberty coinage was minted at the main United States Mint in Philadelphia, as well as the branch mints in New Orleans, San Francisco, and Carson City.
Barber (1892-1915)
Obverse: Lady Liberty
Reverse: A bald eagle
Liberty Head ("Barber") designs appeared on United States minor silver coinage (the dime, quarter, and half dollar) from 1892 to 1916. They derive their common name from their designer, Chief Engraver Charles E. Barber.
Walking Liberty Half Dollar
Obverse: Lady Liberty walking and holding an olive branch
Reverse: A perched bald eagle
Walking Liberty Half Dollar A silver half dollar coin issued by the United States government, equal to 50 cents. Walking Liberties were minted from 19161947. The coin is named after its representation of Liberty on the obverse. The coin's obverse and reverse was designed by Adolph A. Weinman and his mark, AAW, appears under the eagle's wing feathers on the reverse.
Franklin Half Dollar
Observe: Benjamin Franklin
Reverse: Liberty Bell
The Franklin half dollar is a coin of the United States, minted from 1948 to 1963. The coin pictured Benjamin Franklin on the obverse and the Liberty Bell on the reverse. A small eagle to the right of the bell was necessitated by law; ironically, Franklin himself had opposed the selection of the eagle as the US national symbol, preferring the turkey as a "more noble bird". A bill rushed through Congress after the assassination of John F. Kennedy caused the Franklin half to be replaced by the current Kennedy half dollar in February 1964, nine years before the design would otherwise have been eligible for a change.
Kennedy Half Dollar
Observe: President John F. Kennedy
Reverse: The Coat of Arms of the President of the United States
Evolving from the Franklin half dollar, the Kennedy half dollar is a coin of the United States first minted in 1964. This coin was first struck in 1964 less than a year after the assassination of President John F. Kennedy. The front features the face of President John F. Kennedy on the obverse and an eagle on the reverse. The obverse was designed by Gilroy Roberts and the reverse was designed by Frank Gasparro.
