Grading the Kennedy Half Dollar

The Kennedy half (1964–present) changed metal three times: 90% silver in 1964, 40% silver 1965–1970, and copper-nickel clad from 1971 on. Wear shows first on Kennedy's cheek and the eagle's shield. Famous varieties include the 1964 Proof 'Accented Hair,' the 1974-D doubled die, and the 'No FG' coins; the 1970-D (Mint-Set-only) is the key business strike.

Other points to check

Common weak-strike areas

Strike designations

No official full-strike designation exists for Kennedy halves; CAM/DCAM are proof finish designations, not strike-completeness designations.

Grading circulated coins

Most halves circulated lightly after 1964 (many never circulated), so survivors are usually AU–MS. Grade off the cheek and hair spots, and check the eagle's shield and tail feathers for flattening; AU shows just a trace of friction on the cheek and shield with most luster present.

Grading Mint State coins

The prime focal area is Kennedy's cheek and the field around the portrait, where contact marks and luster breaks cap the grade; on the reverse, marks on the eagle's shield/breast matter most. Heavily produced 1964 issues are hard to find truly mark-free, so high MS grades carry premiums.

Proof grading

Proofs from S (1968+) and earlier P (1964). Cameo / Deep Cameo matter, especially for 1964 (including 1964 Accented Hair DCAM). The 1998-S matte proof and 2014 reverse/enhanced finishes are graded as special strikes; watch for artificially frosted cameos.

Common problems

Signs of cleaning or damage

Toning

1964 (90%) and 1965–1970 (40%) silver coins tone like other silver (album/rainbow); clad issues tone less and can develop spotting.

Counterfeit & alteration risks

  • Altered/added 'Accented Hair' or faked DCAM on 1964 proofs
  • Counterfeit or altered 2014-W gold anniversary coins
  • Faked No-FG and 1974-D DDO attributions

For the advanced grader

Identify the composition first (1964 silver, 1965–1970 40% silver, 1971+ clad; 2019+ silver proofs are .999), since it drives value and authentication. Grade MS coins off the large open cheek and the eagle's shield where marks and luster breaks concentrate; with no strike designation, premiums ride on surface preservation plus CAM/DCAM for proofs.
