1965 Kennedy Half Dollar Special Mint Set : A Collector’s Guide

By Charles Morgan and Hubert Walker for CoinWeek Notes …..
 

By the early 1960s, worldwide silver consumption had reached levels too high for the United States Mint to continue using it as a circulating medium. Despite a rise in production, demand for the industrial metal was so great that the basal value of American silver coins had risen beyond the coins’ face value. Speculators took full advantage, leading to a run on the nation’s silver stockpile – which, by 1963, was rapidly diminishing.

The Treasury Department and the Bureau of the Mint apportioned undue blame on coin collectors and silver speculators, but a more sober assessment might have revealed that the more likely culprits were vending machines and pay phones – those once ubiquitous conveniences of the modern age.

Congress’ decision to honor President Kennedy on the 50-cent coin only exacerbated the problem. When the 1964 Kennedy Half Dollar was issued on March 26, 1964, the coin was immediately hoarded. President Lyndon Baines Johnson pushed Congress to act, which it did by passing the Coinage Act of 1965. The law eliminated silver from the dime and quarter, replacing it with a copper-nickel clad sandwich metal, and reduced the amount of silver in half dollars to 40%. The composition of the silver dollar, a denomination not issued since 1935, remained unchanged.

The Coinage Act of 1965 allowed the Mint to simultaneously produce coins in the old and new tenor, which it did to maintain a flow of coins in commerce. The .900 fine silver coins were antedated 1964, while the new clad coins used 1965 as a starting date.

Interestingly, production of the 1965 Kennedy Half Dollar did not commence until 1966. During this time, the Mint briefly discontinued the use of mintmarks to denote whether a coin was struck a branch mint. This is why the “S” mintmark does not appear on the 1965 Kennedy Half Dollar Special Mint Set coin, despite it being struck at the San Francisco Assay Office.

Mint Suspends Proof Coin Production, Offers Special Mint Sets Instead

When the United States Mint resumed its Proof coin program in 1950, it did not foresee that, by the end of the decade, demand for the special strikings would exceed one million and routinely exceed three million in the early 1960s. Rampant speculation caused by the release of the Kennedy Half Dollar pushed the 1964 set to nearly four million! That same year, the Mint’s Annual Uncirculated Coin Set surpassed one million units sold for the first time in its history.

The Mint had had enough, announcing in 1965 that it would suspend the Proof and Mint Set programs and offer collectors Special Mint Sets made up of special coin strikings instead.

The 1965 Special Mint Set included all five circulating coins sealed in the same Pliofilm sleeve that the Mint used to house Proof sets starting in 1955. The cost of the set was $4 ($39.66 in 2024 Inflation-Adjusted Dollars), nearly double the cost of the preceding years’ Proof sets. The San Francisco Assay Office struck 2,830,000 sets in early 1966; only 2,360,000 sold.

Collecting the 1965 Kennedy Half Dollar Special Mint Set Coin

Lest one gets confused by the astonishing prices realized by the Noteworthy Specimens included below, the 1965 Special Mint Set–and, by extension, the 1965 Kennedy Half Dollar Special Mint Set coin–is common and can be purchased in original government packaging for $10 and sometimes less. This price is considerably lower than the inflation-adjusted original cost and is derived from the basal value of the 40% silver half dollar.

Special Mint Set coins are typically of Gem quality or better, but no coin produced for these sets will ever be completely free of contact marks or other issues due to production methods.

Given the Proof-adjacent nature of the manufacturing process, a minority of 1965 Kennedy Half Dollar Special Mint Set coins exhibit Cameo or Deep Cameo/Ultra Cameo contrast. Collectors have paid more attention to these coins in recent years.

The nomenclature used by the grading services is somewhat confusing as PCGS once used “MS” (“Mint State”) on its labels, only to later adopt “SP” (“Specimen”). NGC continues to use “MS”, but notes on its label that the coins are from the Special Mint Sets. CAC has adopted the most straightforward naming convention, using the acronym “SMS”.

Design

Obverse:

The obverse of the Kennedy Half Dollar was designed by Gilroy Roberts, Chief Engraver at the United States Mint from July 22, 1948, to February 11, 1965. Roberts also designed President Kennedy’s inaugural medal, which served as the basis of the present design.

The central motif is an effigy of the 35th President of the United States, the late John Fitzgerald Kennedy. A war hero and (at the time) the youngest person ever to serve as president, Kennedy was inaugurated on January 20, 1961, and assassinated on November 22, 1963. The nation’s grief was such that Congress and the Mint rushed through a design change on the half-dollar denomination to commemorate the bereaved president.

Atop the upper half of the rim is the inscription LIBERTY, with Kennedy’s hair covering the bottom portions of the letters “B”, “E”, and “R”. The date 1965 is cradled at the bottom of the coin, while the national motto IN GOD WE TRUST is inscribed in a straight line above the year but divided by the sharp truncation of Kennedy’s neck.

Gilroy Roberts’ initials are located on the truncation line of Kennedy’s bust, above the “WE” on the bottom right side of the coin.

Reverse:

Roberts’ assistant Frank Gasparro designed the reverse. He based the eagle on the presidential coat of arms from the Seal of the President of the United States, which itself is based on the Great Seal of the United States. The presidential seal in its current form was finalized by Harry S. Truman in 1945, though the number of stars on the seal (and hence the coin) went from 48 to 50 as the states of Alaska and Hawaii entered the Union.

The heraldic eagle’s wings and legs spread in four directions. The left talon (viewer’s right) holds a bunch of arrows, a symbol of war, while the right claw (viewer’s left) holds an olive branch, a symbol of peace. It is tradition to have the eagle face one side or the other relative to national circumstances at the time of striking; in this instance, the eagle faces towards the olive branch despite America’s involvement in Vietnam and other conflicts around the world.

Frank Gasparro’s initials FG are between the eagle’s left leg and tail feathers.

A Union shield covers the eagle’s breast. Vertical bars representing the 13 red and white stripes of the American flag run down most of its face, the stripes representing the original 13 colonies of the United States. The top of the shield (a horizontal band is known in heraldry as a chief) features no stars.

Immediately above the eagle’s head is a scroll featuring the motto E PLURIBUS UNUM. The design behind and above the eagle, which consists of 15 rays, nine stars, and a mass of clouds, is called a glory and is a common design element of both heraldry and an earlier period of numismatics.

The legend UNITED STATES OF AMERICA runs clockwise along the top rim of the reverse, while the denomination HALF DOLLAR runs counterclockwise along the bottom. Dots are between the two inscriptions at both ends. Surrounding the eagle is a ring of 50 stars, representing the 50 states of the Union at the time of the coin’s production.

Edge:

The edge of the 1965 Kennedy Half Dollar Special Mint Set coin is reeded.

Designers

Gilroy Roberts was the ninth Chief Engraver of the U.S. Mint, serving from 1948-1965. His work with the Franklin Mint caused the Mint to let him go. He is primarily remembered for his design of the Kennedy Half Dollar obverse.

Frank Gasparro was an American medalist and coin designer. After serving as an assistant engraver to Gilroy Roberts, he became the 10th Chief Engraver of the United States Mint, serving from 1965-1981. Gasparro also designed the Lincoln Cent Memorial Reverse, the Eisenhower Dollar obverse and regular reverse, and the Susan B Anthony Dollar, among other works. He retired from the Mint on January 16, 1981 (View Designer’s Profile).
