United States 1964 half dollar
In late 1963, after the assassination of John F Kennedy, Congress was eager to memorialize him on a coin. THe half dollar was selected because it had the largest format and Benjamin Franklin had few defenders. The Kennedy half dollar, struck in 90% silver in 1964 only, was massively hoarded by the public seeking a souvenir plus rising silver prices drove the bullion value over the face value. Many 1964 dated coins were struck in 1965, to no avail. The alloy was converted to billon (40% silver) in 1965 and struck in that form through 1970 but even that failed to stop the hoarders. In 1971, the mint gave up and struck the half dollar in copper-nickel, which alloy is still in use. The last issue for circulation was in 2001.
