Sinnock Based the Reverse on a Sketch He Did Not Attribute, and the Cold War Made His Initials Controversial

Mint Director Nellie Tayloe Ross had long wanted a Franklin coin and, after seeing Chief Engraver John R. Sinnock's portrait of the Founding Father on a 1933 medal, she asked him to prepare designs for a new half dollar. Sinnock modeled the obverse portrait on a bust by 18th-century French sculptor Jean-Antoine Houdon. The reverse showed the Liberty Bell, which Sinnock based on a sketch by artist John Frederick Lewis that had been used for the 1926 Sesquicentennial commemorative half dollar; Sinnock did not attribute this source at the time, and the connection was only established decades later by numismatic historian Don Taxay. Sinnock died in May 1947 before completing the reverse design, which was finished by his successor Gilroy Roberts. The Commission of Fine Arts objected to both the small reverse eagle (required by statute for all coins larger than the dime) and to the visible crack in the Liberty Bell. Treasury Secretary John W. Snyder approved the design anyway, apparently unwilling to alter what had been Sinnock's final work.1

When the coins were released in April 1948, the public objected to Sinnock's initials JRS, which appeared at the bust truncation. Many letter-writers insisted the initials referenced Joseph Stalin. The Mint responded with what Walter Breen later described as outraged official denials. The accusation had no merit; Stalin had no middle name beginning with R. The Roosevelt dime, also designed by Sinnock and bearing his initials JS, had drawn the same accusation two years earlier. The initials remained unchanged through 1963. This episode is worth knowing not because it reflects anything about the coin's design quality but because it illustrates accurately how numismatic controversies can outlive their factual basis in specialist discussions long after the original claim was settled.2

Full Bell Lines: What They Are and Why They Control the Series' Premium Market

The Liberty Bell on the reverse carries two sets of horizontal lines near its base, and the completeness of those lines on a given coin is the defining collecting distinction in the Franklin half dollar series. Both PCGS and NGC designate qualifying business strikes as Full Bell Lines (FBL). PCGS requires complete separation of the lower set of lines; NGC additionally requires the upper set to be complete. A Franklin half dollar with the FBL designation in Gem (Mint State 65 or finer) is a substantively different coin from one without it, and the price differential can be enormous: a common date in Mint State 65 trades modestly, while the same date with FBL in the same grade can trade at multiples. The distinction does not merely describe strike quality as an aesthetic preference; it separates coins that were struck with fresh, sharp dies from those that were struck with dies already in degraded condition. Most Franklin halves were struck with dies that had seen considerable use before the lines were compromised.3

The 1953-S FBL Is the Series' Defining Rarity. Fewer Than 50 Are Known.

Among the 35 date-mint combinations in the series, no business strike approaches the difficulty of the 1953-S with Full Bell Lines. The San Francisco Mint struck half dollars that year with dies that produced conspicuously weak details on nearly every coin; the same problem affected 1953-S Jefferson nickels simultaneously, which suggests a die preparation issue at that facility that year rather than a problem specific to the half dollar. Of the 4,148,000 1953-S half dollars struck, approximately 69 examples with FBL characteristics have been certified across PCGS, NGC, and CAC combined. Most of those that do exist were struck very early in the die's use, before degradation was complete, and consequently surface in the upper Mint State grade range. An 1953-S FBL in Mint State 65 is a genuine rarity that commands five figures; the record auction result is $69,000 for an example graded PCGS Mint State 66 Full Bell Lines, realized at Bowers and Merena in 2001.4

Other significant FBL conditional rarities in the series include the 1949-S, which is notoriously poorly struck and rare in any Mint State grade with full lines; the 1955 Philadelphia issue, which has the lowest mintage of any regular business strike in the series at approximately 2,498,000 and is rare at Mint State 66 FBL or higher; and the 1952-S and 1951-S, both of which reflect the San Francisco Mint's chronic difficulty with this design throughout the early 1950s. None of these approaches the 1953-S FBL in absolute rarity, but all represent genuine collecting targets that require sustained search programs at the Gem level.5

The Franklin half dollar is one of the more accessible series in 20th-century silver coinage for the collector working in circulated grades or common-date Mint State. It is one of the least accessible for the collector who defines completion as a full date-mint run with FBL designation in Gem. Both statements are true simultaneously, which is what makes the series interesting: the entry point is genuinely low, and the ceiling is genuinely high, and the distance between them is occupied by a coherent collecting logic rather than arbitrary premiums.

Proofs Were Struck From 1950 Through 1963

No Proof Franklin half dollars were produced in 1948 or 1949. Beginning in 1950, Proofs were struck annually at Philadelphia and sold as part of the annual Proof sets. The 1950 Proof set is the first of the modern Proof set era and commands a premium as such. Proof Franklin half dollars are generally available in proportion to their original mintages; the earlier issues, particularly 1950 through 1955, were packaged in deteriorating cellophane envelopes that caused environmental damage to many examples, and deeply original, undamaged early Proofs are considerably scarcer than the raw mintage figures suggest. Cameo and Deep Cameo (Ultra Cameo in NGC terminology) examples are rare across the series, as the mirror fields were degraded by die use quickly; fewer than a handful of each date have been certified at the Proof 67 Deep Cameo level or finer. The 1956 Type 1 Proof, distinguished from the common Type 2 by having four separated feathers to the left of the eagle's perch rather than three, is the scarcest regular Proof variety and commands the highest premiums among Proof issues in high grade with deep cameo contrast.6

Building the Set

A type set requires one coin. Any common Philadelphia date from the mid-1950s through 1963 in Mint State 64 or 65 is an inexpensive, attractive representative of the design. A complete date-and-mintmark set of all 35 business strike combinations is a manageable project in circulated grades and accessible in lower Mint State; the challenge concentrates in the early San Francisco issues, which require patience in problem-free, original examples even in grades well short of Gem. A complete FBL set is a long-term specialist project, with the 1953-S FBL representing the single unavoidable obstacle that may take years to resolve. Proofs run parallel to the business strikes and add 14 dates from 1950 through 1963. The controlling specialist reference is Tomaska, Rick, A Guide Book of Franklin and Kennedy Half Dollars (Atlanta: Whitman Publishing, 2010; later editions available), which provides the most thorough date-by-date FBL and Proof population analysis available for this series.7
