What Is 50 Cents
A 50-cent coin is a United States legal tender denomination worth half of one dollar, or 0.50 USD. The U.S. Mint produces the half-dollar coin, which is the physical form of 50 cents in circulation. According to the U.S. Mint, the half-dollar denomination has been issued since 1794, though circulation has declined over recent decades. The coin weighs 11.34 grams and has a diameter of 30.61 millimeters, making it larger than a quarter but smaller than a dollar coin. The U.S. Mint's coin specifications page provides the official technical data for the half-dollar and other denominations.
The 50-cent piece is not commonly used in everyday transactions, but it remains a valid form of payment at face value. Banks and retailers are required to accept it as legal tender under federal law. The coin features the profile of President John F. Kennedy on the obverse, a design introduced in 1964 following his assassination. The reverse design changes periodically to mark anniversaries and special events, as managed by the U.S. Mint's circulating coin program.
History and Composition
Early U.S. half-dollars were made of silver, and the coin's composition changed several times over the centuries. From 1965 onward, the U.S. Mint shifted to a clad composition of copper-nickel outer layers bonded to a pure copper core. This change was part of a broader effort to reduce the cost of producing circulating coins as silver prices rose. The modern 50-cent coin contains no silver in its standard circulation version, though special collector editions may have different metallic content.
The Kennedy half-dollar replaced the Franklin half-dollar in 1964, marking a significant shift in U.S. coin design. The U.S. Mint authorized the new design shortly after President Kennedy's death in November 1963. Production numbers peaked in the mid-1960s but declined sharply as the public hoarded the coins for their silver content before the composition change. Today, the U.S. Mint produces half-dollars primarily for collectors and numismatic markets rather than general circulation.
Value and Collectibility
The face value of a 50-cent coin is 0.50 USD, but its numismatic value can be significantly higher depending on condition, year, and mint mark. Coins from certain years, such as 1964, are highly sought after by collectors due to their silver content and historical significance. The Professional Coin Grading Service and the Numismatic Guaranty Company are two leading third-party grading services that authenticate and grade half-dollar coins for collectors.
Market prices for 50-cent coins vary widely based on rarity and grade. A worn 1964 Kennedy half-dollar may trade near its silver melt value, while a pristine uncirculated example can command a premium of several hundred dollars or more. Investors and collectors track coin values through price guides and auction records, and the U.S. Mint's official site provides current mintages and release information for new half-dollar issues.
