The finest known circulation strike 1964 Kennedy Half Dollar is a single example from the Denver Mint which has been graded PCGS MS68. This issue has not changed hands publicly, but would almost certainly establish a price record for the issue. Just under 70 examples have been graded MS67 by PCGS, with the number split between coins from Philadelphia and Denver. When offered for at auction, the sales prices have varied widely from just over $1,000 to a high of $2,820 based on the eye appeal of the particular example.
The grading firm NGC has not graded any circulation strikes at the MS68 grade level. The finest known pieces at this service include 65 examples graded MS67. Only a dozen are Denver Mint issues, with the remained from Philadelphia. The NGC MS67 graded examples have seen lower selling prices, ranging from around $700 to just over $1,000.
It’s also worth noting that there are some high grade coins wich are offered as specimen strikes, meant as prototypes for the SMS coins struck between 1965 and 1967. The finest of these are two SP-69 examples, graded by NGC, one of which sold for $ 16,100 in July 2003. It has to be noted, however, that these are classified as different from regular circulation strike or proof 1964 half dollars.
The finest Proofs graded by PCGS with the Deep-Cameo designation are 79 PR69DCAM’s. There have also been 248 coins graded as PR69CAM, and more than 2,000 pieces without a designation graded PR69. There have been 29 examples of the 1964 Proof Kennedy Half Dollar graded PCGS PR70, one of which sold for $9,400. The examples graded PCGS PR69DCAM have sold for prices ranging from about $1,500 to $2,500.
At NGC, there have been 109 pieces graded PF69 Ultra Cameo, 555 pieces graded PF 69 Cameo, and nearly 3,000 pieces graded PF 69 without designation. There have been no coins graded at the PF 70 level. Prices for the examples graded NGC PF 69 Ultra Cameo tend to range from about $1,000 to $1,500.
For the accented hair variety, which is much more difficult to find with Cameo contrast, PCGS has graded only nine PR68DCAM’s, along with nine PR69CAM’s and 48 PR69’s. NGC has graded two examples of the variety as PF 69 Ultra Cameo and ten PF 68 Ultra Cameo’s. NGC has also graded 35 pieces as PF 69 Cameo. The highest price paid for an accented hair Kennedy Half, at public auction, was $12,650 for a PCGS PR68DCAM in 2008. Another example in the same grade sold for $ 11,500 a year later.
