When hunting for valuable coins, it's essential to know that not all Kennedy half dollars are created equal, especially when it comes to silver content. Discovering which years hold the precious metal can turn a pocketful of change into a valuable find. The story of their composition is a fascinating one, marking a transition in U.S. coinage.
The most sought-after year is the very first one. All Kennedy half dollars minted in 1964 are composed of 90% silver. Introduced to honor the late President John F. Kennedy, this initial issue is the only year the coin was struck with this high silver content for general circulation, making it a key piece for any collector.
Following the inaugural year, the U.S. Mint began a gradual reduction of silver. From 1965 through 1970, Kennedy half dollars were made with a 40% silver clad composition. While they don't have the high silver content of the 1964 coin, they still contain a significant amount of silver and are certainly worth holding onto.
After 1970, the era of silver in circulating American currency effectively ended. Kennedy half dollars minted from 1971 to the present day for general circulation contain no silver at all; they are made from a copper-nickel clad composition. The only exceptions are special silver proof sets and other commemorative issues produced specifically for collectors by the U.S. Mint, which can contain 90% or even 99.9% silver. So, for coins you might find in circulation, the key dates to remember are 1964 for 90% silver and 1965 to 1970 for 40% silver.
