1967

The 1967 is the final no-mintmark Kennedy and the highest-mintage half dollar of the silver-clad era at 295,046,978 reported, almost three times the 1966 figure and nearly four and a half times 1965. The output reflected the Treasury's strategy of flooding the market with enough coins to satisfy hoarding pressure and end the shortage; by 1967 it largely worked, which set up the return of mintmarks in 1968. Composition stayed at 40% silver-clad with .800 fine outer layers bonded to a .209 silver core, 11.50 grams gross and .14792 troy ounce net silver. Special Mint Sets continued for collectors in lieu of proofs; the SMS 1967 is a separately catalogued proof entry. Business strikes from Philadelphia and Denver bear no mintmark and cannot be distinguished by branch.

Strike quality is the best of the three no-mintmark dates. Dies were turned over routinely under the high-volume schedule, and detail on Kennedy's hair above the ear and the eagle's chest feathers averages noticeably crisper than on either 1965 or 1966. The 40% silver-clad authentication tell remains a thin reddish line of exposed copper-rich core at the edge, and the surface alloy still picks up contact marks on the cheek and jawline more readily than the 1964 90% silver coin did. Where the 1967 is unusual is in how often genuinely clean MS66 and MS67 surfaces turn up in old mint set packaging. Population reports at the major grading services consistently show 1967 ahead of 1965 and 1966 in MS66+ even adjusted for mintage, almost certainly a function of better die maintenance combined with more aggressive collector preservation as the shortage eased.

The 1967 is a common date in any grade through MS66 and a condition issue mostly at MS68, which is where premiums begin to matter. Mint set provenance in original government packaging is easier to verify here than for 1965 or 1966 because dealer supply chains preserved more sealed sets intact. Year-set and composition-type builders can typically buy this date raw with confidence; certification is worth the cost only at the upper grade tiers.
