What Half Dollars Are Made of Silver?
Uncover which U.S. half dollars contain silver, how to identify them, and how to determine their intrinsic and collector value.
The United States half dollar, a coin with a rich history, has undergone several transformations in its metallic composition. Initially, these coins contained a significant amount of silver, but economic shifts and rising metal prices led to changes. The alteration reflects broader monetary policy adjustments, moving away from precious metal coinage for general circulation. Understanding which half dollars contain silver and how to identify them helps distinguish between common coins and those that hold intrinsic metal value.
Identifying Silver Half Dollars
Identifying silver half dollars involves examining their date of mintage and physical characteristics. Half dollars minted in 1964 and earlier contain 90% silver and 10% copper. This category includes designs such as the Walking Liberty (1916-1947), Franklin (1948-1963), and the 1964 Kennedy Half Dollar.
Following 1964, the U.S. government reduced the silver content. Kennedy Half Dollars minted from 1965 to 1970 contain 40% silver, with the remainder being copper. These coins are often referred to as “silver-clad” because their composition consists of an outer layer of 80% silver and 20% copper bonded to a pure copper core. Half dollars produced from 1971 onward contain no silver, being made from a copper-nickel clad composition.
Inspect the coin’s edge for identification. A 90% silver half dollar will display a solid silver-colored edge. In contrast, 40% silver half dollars show a faint copper line on their edge. Modern clad coins will reveal a distinct copper stripe sandwiched between two nickel layers on their edge. Silver coins often possess a unique luster and a brighter, whiter appearance compared to the duller finish of copper-nickel clad versions.
Calculating Silver Melt Value
Silver melt value represents the intrinsic worth of a silver half dollar based solely on its precious metal content, separate from any collector or numismatic value. The melt value fluctuates with the current market “spot price” of silver.
To calculate melt value, you need the coin’s specific silver content in troy ounces, its silver fineness (e.g., 90% or 40%), and the current market spot price of silver per troy ounce. For 90% silver half dollars, each coin contains approximately 0.36169 troy ounces of pure silver. A 40% silver Kennedy Half Dollar contains about 0.1479 troy ounces of pure silver.
The calculation involves multiplying the pure silver content of the coin by the current spot price of silver. For instance, if the live silver spot price is $38.10 per troy ounce, a 90% silver half dollar would have a melt value of approximately $13.78. Similarly, a 40% silver half dollar would have a melt value of approximately $5.63. Current silver spot prices are readily available on financial news websites and commodity market data platforms.
Understanding Numismatic Value Drivers
Beyond their intrinsic metal content, many silver half dollars can command a higher value among collectors due to numismatic factors. The physical condition, or grade, of a coin influences its collector value. Coins that show minimal wear, retain their original luster, and have few scratches or marks are more desirable and valuable than heavily circulated pieces. Coin grading systems, such as the Sheldon Scale, assess condition on a numerical scale, with higher numbers indicating better preservation.
Rarity and mintage numbers also play a role in determining a coin’s appeal to collectors. Coins produced in smaller quantities, known as low mintage issues, are rarer and more sought after. Specific dates within a series might have low production figures, making them “key dates.” The actual number of surviving coins, rather than just the original mintage, further impacts rarity.
Mint marks, small letters or symbols indicating where a coin was produced, can also affect its value. Different mints (e.g., Philadelphia, Denver, San Francisco) had varying production numbers for specific dates, meaning a coin from a mint with lower output for that year could be more valuable. For example, a coin without a mint mark indicates it was produced at the Philadelphia Mint during periods when it did not use a mark.
Identifiable minting errors and varieties can increase a coin’s collector value. These anomalies occur during the manufacturing process and can include doubled dies, where design elements appear duplicated, or off-center strikes, where the design is not perfectly centered on the coin. Other errors might involve coins struck on the wrong metal planchet or those with re-punched mint marks. Such unique characteristics make these coins desirable to specialized collectors.
