The Kennedy half dollar remains the largest denomination of U.S. coinage still in circulation. First issued in 1964, it was created to honor President John F. Kennedy after his assassination on November 22, 1963. Designed by Gilroy Roberts (obverse) and Frank Gasparro (reverse), the coin gained immediate popularity among collectors and citizens alike.
Transition to Copper-Nickel Composition
Before 1971, Kennedy half dollars were made with silver—initially 90%, then 40%. Starting in 1971, the U.S. Mint transitioned the coin’s composition to a copper-nickel clad alloy, removing silver entirely. This change makes the 1971 half dollar historically significant as the first of its kind with no silver content. It weighs 11.34 grams, has a 30.61 mm diameter, and features a reeded edge.
Obverse Design by Gilroy Roberts
The obverse features a dignified left-facing portrait of President Kennedy. The word “LIBERTY” arcs above his head, while “IN GOD WE TRUST” is split below the neckline. The mint date appears at the bottom, with mint marks when applicable. Gilroy Roberts’ initials “GR” appear subtly on the truncation of Kennedy’s neck.
Reverse Design by Frank Gasparro
On the reverse, Gasparro incorporated the Presidential Seal—a heraldic bald eagle holding arrows and an olive branch, symbolizing war readiness and peace. Above the eagle is the Latin motto “E PLURIBUS UNUM.” A ring of 50 stars encircles the eagle, with “UNITED STATES OF AMERICA” above and “HALF DOLLAR” below. This design remained until 1975 when it was replaced for the U.S. Bicentennial.
1971 Kennedy Half Dollar Varieties and Mint Marks
In 1971, the coins were struck at three U.S. Mint locations: Philadelphia (no mint mark), Denver (“D”), and San Francisco (“S” for proofs). Philadelphia minted over 155 million coins, Denver over 302 million, and San Francisco about 3.2 million proof coins. Most circulated heavily, so high-grade specimens are scarce and valuable.
Value of the 1971 Half Dollar
In circulated condition, 1971 half dollars usually sell for face value or slightly more—around $0.60. Uncirculated examples have higher premiums. A no mint mark coin in Mint State 67 has sold for over $2,200. Denver-minted versions in top condition have reached auction prices as high as $13,000. San Francisco proof coins range from $4 to $18 depending on grade and cameo contrast.
Key Grading Insights
Collectors rely on the Sheldon Scale to assess a coin’s condition. Grades range from 1 (Basal State) to 70 (Perfect Mint State). Most circulated 1971 halves grade between 10 and 40. Mint State coins (60 and above) are sought-after, especially in pristine condition with minimal contact marks.
Rare and Notable Error Coins
The 1971 Kennedy half dollar is known for several rare mint errors due to the transition to copper-nickel planchets. These include coins mistakenly struck on leftover 40% silver planchets, which can sell for over $10,000. Other known errors are strikes on nickel or penny planchets, off-center strikes, double die obverses or reverses, and clipped planchets—each increasing the coin’s value significantly.
How to Identify a Silver Error Coin
To check if a 1971 half dollar is silver, examine the coin’s edge. A solid silver stripe indicates silver content, while a visible copper line confirms it’s clad. Silver coins are also slightly heavier and non-magnetic.
