The United States minted Kennedy half dollars composed of 90% silver in 1964, the year following President Kennedy’s assassination. The silver content was subsequently reduced to 40% for coins produced between 1965 and 1970. These years represent the specific period when the circulated half-dollar coins contained a significant amount of the precious metal.
Understanding the years of silver composition is important for coin collectors and investors because the intrinsic value of these coins is tied to the fluctuating price of silver. The presence of silver significantly increases the worth of these coins beyond their face value, making them desirable assets. This era reflects a transition in U.S. coinage away from precious metal content due to rising silver prices and increased demand.
Therefore, the following sections will delve into the specifics of each period, examining the composition, mintage figures, and factors influencing the value of these coins minted with varying silver percentages.
1. 1964
The year 1964 is intrinsically linked to the question of which Kennedy half dollars contain silver. The Kennedy half dollar, first minted in 1964 following President John F. Kennedy’s assassination, was composed of 90% silver and 10% copper. This specific composition makes the 1964 coins a distinct and valuable category within the broader scope of Kennedy half dollars. The high silver content was a direct response to the commemorative nature of the coin and prevailing coinage standards at the time. For instance, a collector seeking silver Kennedy half dollars would immediately focus on 1964 as a key year due to this high silver percentage.
The significance of the 1964 issue extends beyond its composition. It represents the last year in U.S. coinage where circulating silver coins were struck with such a high silver content. Rising silver prices and increasing demand soon led to a reduction in silver content for subsequent years. Examples of this are seen in the transition to 40% silver in later Kennedy half dollars, and the eventual elimination of silver from dimes and quarters. The 1964 coin, therefore, serves as a benchmark and a tangible representation of an era in American coinage.
In summary, the 1964 Kennedy half dollar, with its 90% silver composition, stands as a crucial data point when determining which years these coins contained silver. Its high silver content distinguishes it from later issues and underscores its historical and intrinsic value. Recognizing this connection is essential for collectors, investors, and anyone interested in understanding the evolution of U.S. coinage.
2. 1965-1970
The period from 1965 to 1970 represents a distinct phase in the history of Kennedy half dollars relative to their silver content. These years are crucial in addressing the inquiry of which Kennedy half dollars contained silver, as they mark a transition from the initial 90% silver composition to a reduced 40% silver-clad format.
-
Composition and Cladding
During 1965-1970, Kennedy half dollars were produced using a silver-clad composition. This involved an inner core of 20.9% silver and 79.1% copper, bonded to outer layers of 80% silver and 20% copper. The resulting coin contained approximately 40% silver by weight. This cladding technique was implemented as a cost-saving measure due to rising silver prices, representing a significant departure from the 90% silver coins of 1964. This adjustment directly impacts the intrinsic value and collectibility of these specific coins.
-
Congressional Mandate and the Coinage Act of 1965
The transition to the silver-clad Kennedy half dollar was enabled by the Coinage Act of 1965. This legislation authorized the reduction of silver content in dimes and quarters, and the introduction of clad metal compositions for half dollars. Congress enacted this law to alleviate the strain on the nation’s silver reserves caused by increasing coin demand and speculative hoarding. The act reflects a pivotal moment in the shift from silver-based coinage to base-metal coinage in the United States.
-
Mintage Figures and Market Value
The mintage figures for Kennedy half dollars between 1965 and 1970 are generally high compared to the 1964 issue. Although the reduced silver content lowered the individual intrinsic value of each coin, the overall cumulative silver content of these coins maintains a degree of interest among precious metal investors. Coins in uncirculated condition, or those with unique minting errors, command a premium among collectors.
-
Distinguishing Features and Identification
Visual inspection alone is insufficient to definitively determine the silver content of a Kennedy half dollar. However, knowledgeable collectors often use a weight test or edge examination to differentiate between the 40% silver-clad coins and those produced later with no silver. Precise measurements of weight can indicate silver content, while the absence of a visible copper stripe on the edge may suggest a higher silver composition. The edge of the 40% coins has a visible layer of copper.
The years 1965 to 1970 are pivotal in the discussion regarding the silver content of Kennedy half dollars. They represent a deliberate reduction in silver usage driven by economic factors and legislative action. While not composed of the same high silver content as the 1964 issue, these years produce a significant number of half dollars that still retain substantial intrinsic and collectible value based on their silver composition.
3. Silver Composition
The silver composition of Kennedy half dollars is the determining factor in identifying which years the coins contained the precious metal. The presence and percentage of silver directly correlate to the coin’s intrinsic value and collectibility, making it a central point of inquiry.
-
90% Silver (1964)
The 1964 Kennedy half dollars, composed of 90% silver and 10% copper, represent the highest silver content within the series. This composition resulted from a legislative decision to commemorate President Kennedy shortly after his assassination. The high silver content makes these coins particularly valuable for both collectors and those seeking to acquire silver bullion. Its worth far exceeds its face value.
-
40% Silver (1965-1970)
From 1965 to 1970, Kennedy half dollars were produced with a 40% silver content. This was achieved through a cladding process, where layers of silver alloy were bonded to a core of copper alloy. This reduction in silver was a response to rising silver prices and a shortage of the metal. This coin have less value than 90% composition because of less silver content.
-
Base Metal (1971-Present)
Beginning in 1971, the Kennedy half dollar was no longer minted with any silver content for general circulation. These coins are composed of a copper-nickel clad composition, similar to dimes and quarters produced during the same period. The absence of silver significantly reduces their intrinsic value, making them primarily worth their face value unless in exceptional condition or with collectible errors.
-
Impact on Value and Collectibility
The silver composition of a Kennedy half dollar directly affects its value in the numismatic market. Coins with higher silver content, such as those from 1964, command significantly higher prices than later issues lacking silver.

6. Metal Content
Metal content is the definitive attribute that distinguishes silver-containing Kennedy half dollars from those without, directly answering the question of “what years were Kennedy half dollars silver.” The composition of the coin dictates its intrinsic value, collector appeal, and historical significance.
-
90% Silver Composition (1964)
The 1964 Kennedy half dollars were struck with a 90% silver and 10% copper alloy. This high silver content signifies the coin’s commemorative purpose and reflects the prevailing U.S. coinage standards of the time. As an example, a 1964 Kennedy half dollar contains approximately 0.7234 troy ounces of silver, making it highly sought after due to its bullion value and historical importance. This high silver percentage is absent in subsequent years, setting the 1964 coin apart.
-
40% Silver Composition (1965-1970)
From 1965 to 1970, Kennedy half dollars were produced with a silver-clad composition consisting of an outer layer of 80% silver and 20% copper bonded to an inner core of 20.9% silver and 79.1% copper. This resulted in a coin that was 40% silver by weight. This change was mandated to reduce silver consumption during a period of rising silver prices. A key implication is that these coins have less silver and lower intrinsic value compared to the 1964 issue but still retain considerable collectibility. These coins have approximately 0.1479 troy ounces of silver.
-
Base Metal Composition (1971-Present)
Beginning in 1971, Kennedy half dollars ceased to contain silver for general circulation. These coins are composed of a copper-nickel clad composition, similar to dimes and quarters produced in the same era. The absence of silver significantly diminishes the intrinsic value of these coins, rendering them worth only their face value unless in exceptional condition or exhibiting numismatic errors. This shift marked the complete transition from silver-based coinage to base-metal coinage for Kennedy half dollars intended for general use.
-
Identification Techniques and Verification
Differentiating between silver and base metal Kennedy half dollars requires careful examination. The edge of the coin is a key indicator. Silver-clad coins (1965-1970) exhibit a visible copper stripe on the edge, revealing the clad composition. In contrast, the 1964 coins, being 90% silver, display a uniform silver color throughout. Coins from 1971 onward also show a clad layer without silver. Furthermore, weight differences can provide clues, though this method is less precise. More sophisticated techniques, such as X-ray fluorescence analysis, can provide definitive confirmation of the metal content.
In summary, the metal content of Kennedy half dollars serves as the primary means of identifying “what years were Kennedy half dollars silver.” The 1964 issues contained 90% silver, the 1965-1970 issues contained 40% silver, and issues from 1971 onward contain no silver for general circulation.
