1964

Released on March 24, 1964, exactly four months and two days after the Dallas assassination, the 1964 Kennedy half is the first issue of a memorial design pushed through Congress at unusual speed. Public Law 88-256, signed December 30, 1963, authorized Gilroy Roberts's adapted inaugural-medal portrait and Frank Gasparro's heraldic eagle reverse, and waived the standard 25-year rule on existing designs. Philadelphia struck 273,304,004 pieces of this coin, by a wide margin the largest Kennedy mintage from that mint until the late 1960s, yet within weeks of release the issue had vanished from cash registers. Buyers carried examples home as keepsakes rather than spending them, and the 90% silver content (12.50 g, 0.36169 oz of fine silver) gave hoarders a second reason to set them aside as bullion prices stirred.

For a date with a quarter-billion-plus mintage, the 1964 reads surprisingly tough in high grade. The portrait sits in noticeably high relief for a circulating half, and that relief translates into bag-mark concentration on Kennedy's cheek and jawline plus weakness on the eagle's central shield lines. Circulated survivors are everywhere in EF and AU, but original Mint State pieces with clean cheeks step up sharply above MS65, and the gem ceiling at MS66 and MS67 is where premiums start to matter. Collectors should look for unbroken luster across the obverse fields and check the high points of the eagle's breast feathers under a glass before paying a grade premium. Roberts's initials GR appear at the truncation of Kennedy's neck; Gasparro's FG sits to the right of the eagle's tail feathers.

Within the series, the 1964 functions as the type coin for the 90%-silver Kennedy, the only year struck at that fineness in business-strike format before the Coinage Act of 1965 dropped half-dollar silver content to 40%. It is a common date in any grade through MS64, a condition issue from MS66 upward, and an essential year-set anchor for anyone building the design. Raw examples sell as bullion-plus-numismatic, and certification matters mainly above MS65.
