Hello! That's a great question, as the value of a Kennedy half-dollar can vary quite a bit depending on its year and composition. While the provided context points to some excellent coin value websites, the text itself doesn't list the specific prices. Based on general knowledge, here is a breakdown of what makes these coins valuable.
The most important factor for most Kennedy 50-cent pieces is their silver content. The 1964 Kennedy half-dollar is a key date because it's made of 90% silver. Its value is primarily tied to the current price of silver, which often puts it in the range of $9 to $12, or even more depending on the market.
From 1965 to 1970, the composition was changed to a 40% silver-clad mix. These coins are also worth more than their face value due to their silver content, but less than the 1964 version. Their value typically fluctuates between $3 and $5.
Starting in 1971, the U.S. Mint removed all silver from circulating Kennedy half-dollars. Any coin dated 1971 or later that you find in your pocket change is made of a copper and nickel alloy and is generally only worth its face value of 50 cents.
Of course, condition matters a lot. Uncirculated coins from any year will be worth more to collectors. Special issues, like proof coins from mint sets, and coins with rare errors or varieties can also be significantly more valuable. For a precise value on a specific coin, checking a current price guide or consulting a reputable coin dealer is always a good idea
