The 1952 Franklin Half Dollar Value Guide

The Full Bell Lines (FBL) designation is awarded by PCGS or NGC when the seven parallel horizontal incuse lines at the bottom of the Liberty Bell reverse are complete and uninterrupted across their full width. This designation is not merely cosmetic — it confirms the coin received an unusually sharp, full-pressure die strike, which was the exception rather than the rule in 1952 production.

To qualify for FBL, the obverse must also pass inspection: the three wisps of hair to the right of Franklin's ear must be clearly distinct and not blended together. Finding both conditions met on the same coin — especially in gem MS-65 or higher — is genuinely difficult for the 1952 Philadelphia issue, where striking quality was inconsistent across die pairings.

The dramatic premium for FBL examples explains why serious collectors pursue them. A standard 1952-P in MS-65 might sell for $70–$200, while the same coin with FBL status can fetch several hundred to several thousand dollars depending on grade. The sole finest PCGS MS-67+ FBL example, graded with a green CAC sticker, sold for $42,300 in January 2019 — establishing one of the most remarkable premiums in the Franklin half dollar series.

The Bugs Bunny variety (PCGS FS-401) is a die clash error occurring when the obverse and reverse dies struck each other without a planchet between them. This contact transferred the incuse image of the eagle's wing feathers from the reverse die onto the obverse die. When the dies subsequently struck a planchet, the transferred feather traces appeared as raised lines on Franklin's portrait.

On the 1952 Philadelphia issue, those die clash marks fall directly at Franklin's upper lip and mouth area, making him appear to have two large protruding front teeth — the precise visual that gave the variety its famous "Bugs Bunny" nickname. The effect is visible to the naked eye on strongly clashed examples, making it an approachable variety for beginning collectors who don't own a loupe.

Collector demand for this variety is driven partly by its memorable nickname and partly by the genuine rarity of high-grade survivors with sharp clash details. An MS-63 example realized $2,447 in 2011; an MS-65+ FBL example sold for $3,150 in 2021. The 1952-S issue also carries a Bugs Bunny designation, listed as a separate PCGS variety, making this die clash type present on two of the three 1952 mints.

The Scarface variety (PCGS FS-402) is the second major die clash error on the 1952 Philadelphia Franklin half dollar. Like the Bugs Bunny, it results from dies contacting without an intervening planchet. However, on this variety the die clash transferred feather or design detail at a different position across the die face, so the resulting marks appear on Franklin's cheek rather than at his mouth.

The transferred die detail creates a raised diagonal line or series of marks running across Franklin's cheek that visually resembles a scar — hence the distinctive nickname. Under magnification the marks reveal their true origin as ghost impressions of design elements from the reverse die, rather than any post-mint damage or scratch. The distinction matters: damage reduces value, while an authenticated die clash increases it.

The Scarface variety receives less collector attention and press coverage than the Bugs Bunny, which means genuinely clashed examples can still be found at modest premiums by informed cherrypickers. However, in gem uncirculated grades with FBL designation, the premium over a normal 1952-P grows substantially. Collectors building a complete set of 1952 die clash varieties will need both the FS-401 and FS-402 to complete that specialized objective.

The Denver Mint's 1952 "Booger" variety (PCGS FS-401 for the 1952-D) is the Denver counterpart to Philadelphia's die clash errors. On this variety, the die clash transferred eagle feather detail from the reverse die onto the obverse die, but the transferred marks fall at a different position relative to Franklin's portrait — specifically near his nostril area.

The resulting raised marks at Franklin's nose were interpreted by collectors as a booger-shaped protrusion from his nostril, giving the variety its irreverent but memorable nickname. While less well-known than the Philadelphia Bugs Bunny, the Booger variety follows the exact same formation mechanism: a die-to-die contact event without an intervening planchet during the minting process. On strong clashes, the feathery marks are visible without magnification.

The 1952-D Booger represents an excellent entry point for die clash variety collecting because Denver pieces in circulated grades remain affordable. In lower grades, confirmed Booger examples sell at modest premiums over bullion. But as grades climb into MS-64 and above — especially with an FBL designation — the premium over a normal 1952-D grows considerably. A Booger FBL example is cataloged separately by PCGS, meaning top-grade survivors are tracked individually in population reports.

The 1952-S/S Repunched Mint Mark (RPM) variety, cataloged as PCGS FS-501, occurs because in 1952 mint marks were individually hand-punched into each working die at the San Francisco Mint rather than being included in the master hub. When a punch was applied twice — even slightly off-alignment — a secondary "S" impression became permanently embedded in the die, appearing on every coin struck from that working die.

On the 1952-S/S FS-501, the secondary "S" is visible above or offset from the primary "S" mint mark position above the Liberty Bell's yoke on the reverse. Under magnification, the doubling appears as a ghostly secondary letter partially overlapping the primary punch. The distance and direction of the repunch can vary by die state, so some examples show bolder RPM effects than others depending on die wear progression.

The 1952-S/S is particularly collectible because the San Francisco issue already commands a premium over Philadelphia and Denver due to its lower mintage of 5,526,000 coins. Layering a confirmed RPM variety on top of an already scarcer base coin creates a compound rarity factor. In higher grades with FBL designation, the 1952-S/S RPM FBL is one of the most challenging 1952 Franklin half dollar varieties to acquire, with a small population in top PCGS and NGC holders.
