Collectors consider these Kennedy half dollars of the greatest quality since the SP in the title indicates that they were part of a special mint series. Only five PCGS-graded SP68s exist. Only one has sold for $150,000.
A 1964 SP68 Kennedy half dollar sold for $156,000 at Stack's Bowers in 2019, per PCGS. The company's archives indicate a higher-grade PCGS-graded SP69 specimen, but no auction to assess its value.
This is numismatics, where detail is crucial. The 1964 Kennedy half dollar's initial striking had curving lines above the ear, where the hair originates. SD Bullion says this “accented hair” version can also be detected by a lower left serif mistake on the I in “Liberty.”
The SD Bullion price record for this coin was $45,600 in December 2022, but Heritage Auctions set a new record of $46,800 in January 2024 (per PCGS).
CoinValueChecker noted that the proof 1968 Kennedy half dollar's San Francisco Mint affiliation was marked by a conspicuous “S”. Before 1968, only Philadelphia minted proof Kennedy half dollars.
Collectors say San Francisco 1968 proof coins were better than Philadelphia ones. Thus, high-grade ones are common.
This is unusual. It has "funkadelic toning on both sides reminiscent of a Grateful Dead T-shirt." Legend Auctions characterized the item as having sharp and excellent surface condition for its level. This rare MS68 coin sold for $22,325 in a February 2018 auction.
