Hey there! That's an excellent question. The value of a Kennedy half dollar based on its silver weight really depends on the year it was made, as the silver content changed over time.
The most valuable Kennedy half dollar in terms of silver is the one from 1964. These coins are composed of 90% silver and contain about 0.36 troy ounces of the precious metal. As one of the sources indicates, these 90% silver coins are often bundled and sold based on their high silver content.
From 1965 to 1970, the US Mint reduced the silver content. The Kennedy half dollars from this period are made of 40% silver, which means they contain significantly less pure silver, about 0.15 troy ounces per coin. They are still worth more than their face value but have less silver value than the 1964 version.
Any Kennedy half dollar intended for circulation minted from 1971 to today contains no silver at all and is just worth 50 cents.
To find the exact current value, you would multiply the coin's pure silver weight by the daily spot price of silver. This price fluctuates, which is why resources like the NGC coin melt value calculator mentioned in the context are so useful for getting a live price. So, be sure to check the date on your coin first
