Grading the Franklin Half Dollar

The Franklin half (1948–1963) is a 90% silver coin with Ben Franklin and the Liberty Bell. The big premium is 'Full Bell Lines' (FBL), coins showing the complete horizontal lines across the bottom of the bell. The standout rarity is the 1953-S, which almost never comes fully struck with FBL.

Common weak-strike areas

Strike designations

Full Bell Lines (FBL): PCGS awards it only to MS60+ coins with full, unbroken LOWER Liberty Bell lines, withholding it when marks, weak strike, or planchet defects break the line continuity (a few light marks are tolerated if continuity is intact). NGC's standard covers more of the bell: it requires both the top and bottom sets of bell lines to be complete and uninterrupted for its FBL designation.

Grading circulated coins

Cheek and hair show wear first; check the bell's lettering and lines for flattening. The lower bell lines are usually incomplete even on circulated coins, so Full Bell Lines is a Mint-State-only consideration. At EF–AU look for light high-point wear on the cheek and bell with most luster intact.

Grading Mint State coins

The large open cheek is the prime focal area, bag marks and chatter there cap the grade, and luster breaks show first on the cheek. The FBL designation is the central value driver.

Proof grading

Proofs 1950–1963 (Philadelphia). Cameo (CAM) and Deep/Ultra Cameo (DCAM) matter greatly; early-1950s cameos are scarce. Watch for artificially frosted fake cameos.

Common problems

Signs of cleaning or damage

Toning

Franklins tone attractively; rich, original album/rainbow toning is prized and can add a strong premium at high grade.

Counterfeit & alteration risks

  • Tooled/altered bell lines on genuine 1953-S coins to fake the high-premium FBL designation
  • Artificially frosted 'Cameo' proofs

For the advanced grader

FBL is a Mint-State-only strike designation requiring unbroken bell lines (PCGS judges the lower set only; NGC requires both the upper and lower sets). PCGS tolerates light marks if line continuity is intact, and S-mint coins (except 1949-S) rarely qualify. Grade the obverse off the large open cheek where marks and luster breaks register. Beware mechanically tooled bell lines (notably on 1953-S) and artificially frosted 'cameo' proofs.
