History of the 1966 Half Dollar

The United States Mint produced the Kennedy half dollar to commemorate President John Fitzgerald  Kennedy, one of the country’s most beloved presidents following his tragic assassination.

Soon after his death, the Treasury, Mint, and the President’s family came together to discuss the creation of a new coin that would monumentalize him. Several coins were up for consideration to be replaced by a Kennedy coin, and after much consultation and forethought, they agreed to replace Benjamin Franklin’s half-dollar.

Chief engraver, Gilroy Roberts, oversaw the coin’s design, ensuring that minting could start immediately.

To save time, Roberts and his assistant, Frank Gasparo, modified a few designs they had created earlier in 1961 of President JFK for the presidential series medal. Roberts worked on the obverse design while Gasparo worked on the reverse.

By December, trial half dollars were minted and the Treasury approved the designs, which became examples from which circulation coins were minted.

The Treasury introduced the first Kennedy half dollars into circulation in March 1964, about four months after the President’s assassination. There was such a high demand for the new coin that all 70,000 half dollars initially offered to the public were sold out by mid-morning.

That year, collectors hungrily hoarded Kennedy half dollars despite the Treasury’s effort to mint more half dollars, eventually leading to a silver shortage.

By 1966, all coins were made from only 40% silver and 60% copper instead of the previous composition of 90% silver and 40% nickel.

That year a total of 108,984,932 half dollars were minted at the Philadelphia mint and released into circulation. The Treasury also commissioned the minting of special mint sets at the San Francisco facility, and 2,261,583 of these coins were minted.

The Kennedy half dollars from 1966 do not feature a mint mark; it can be hard to tell from which mint a 1966 half-dollar came. As part of the popular Kennedy half dollars, the 1966 half dollar is highly sought after among collectors.
