The metallic composition of United States 50-cent pieces is entirely dependent on their year of mintage. The silver content has changed significantly over time, meaning a simple yes or no answer is insufficient.
Historically, from the denomination's introduction in 1794 through 1964, half dollars were composed of 90% silver and 10% copper. These coins are often sought by collectors and investors for their high precious metal content, also known as bullion value.
A major shift in composition occurred in the mid-1960s. For the years 1965 through 1970, the Kennedy half dollar was produced with a debased silver content of 40%. These coins were constructed with outer layers containing 80% silver bonded to an inner core with a much lower silver percentage, creating an overall composition of 40% silver.
Beginning in 1971, silver was completely removed from all circulating half dollars. According to the U.S. Mint, the half dollars produced from that year to the present day have a clad composition. They are made with a pure copper core and outer layers of 75% copper and 25% nickel. Therefore, any U.S. 50-cent piece intended for circulation and dated 1971 or later is not made of silver.
