You've got your hands on a truly special coin! The 1964 Kennedy half dollar is a prized possession for many collectors, not just because it was the first year of issue honoring the late president, but because it's the last U.S. half dollar struck for circulation containing 90% pure silver. This high silver content gives it a substantial intrinsic value that far exceeds its 50-cent face value.
The absolute minimum you should expect your 1964 half dollar to be worth is its silver "melt" value. Based on its 90% silver composition, this value typically hovers around $10, though it fluctuates with the daily spot price of silver. This is the baseline value for a common, circulated coin that shows signs of wear. Price guides from authorities like Greysheet confirm this, placing circulated examples in this approximate $10 to $12 range.
However, the key to unlocking its true potential lies in its condition. If your coin has little to no wear and still retains its original mint luster, it's considered an "uncirculated" or "Mint State" (MS) coin, and its value climbs significantly. A typical uncirculated 1964 Kennedy half dollar can easily fetch between $15 and $40. For coins in exceptionally pristine condition, as graded by services like NGC, the value can soar into the hundreds or even thousands of dollars for the finest known examples.
You'll also want to check for a mint mark on the reverse side. Coins struck in Philadelphia have no mint mark, while those from the Denver mint have a small "D". While values are often similar, the specific condition and mint mark are crucial details for a collector. There are also special proof versions made for collectors and even rare varieties, like the "Accented Hair" proof, that are worth considerably more. So, while every 1964 half dollar is a valuable silver treasure, a close look could reveal it to be an even more valuable collectible.
