When Was the Kennedy Half Dollar First Minted?

By GovMint :

The Kennedy Half Dollar debuted in 1964, just months after President John F. Kennedy's assassination in late 1963. The half dollar was introduced as a tribute to the beloved president, and it quickly became a cherished piece for many Americans. Initially struck in 90% silver, the composition of the Kennedy half dollar changed over the years. Today, it remains a popular collector's item and a significant part of modern U.S. coinage history.
