The Kennedy Half Dollar, introduced in 1964, commemorates President John F. Kennedy following his assassination. The coin features a profile of Kennedy on the obverse and the Presidential Seal on the reverse. The 1971 Kennedy Half Dollar is part of a series minted in order to maintain the coin's circulation. While Kennedy Half Dollars were originally composed of 90% silver, subsequent issues, including the 1971 version, are composed of 40% silver. These coins are collected for their historical significance and silver content, attracting both numismatists and silver investors.
