Hello! That's a fantastic question about the 1972 Kennedy half dollar. The value can be a little tricky because it really depends on which specific version of the coin you have. The search context provided didn't contain the specific price details needed to answer, so I'll happily explain it based on general coin knowledge.
First, it's important to know that most 1972 half dollars are not made of silver. The U.S. Mint stopped using 90% silver for circulating half dollars after 1964. The coins made for general circulation in 1972, which have no mint mark (from the Philadelphia mint) or a "D" mint mark (from the Denver mint), are made of a copper-nickel clad composition. In circulated condition, these are typically worth only their face value of 50 cents. If you have one in pristine, uncirculated condition, it might be worth a few dollars to a collector.
However, there were special collector versions of the 1972 half dollar that do contain silver! These coins were struck at the San Francisco mint and will have an "S" mint mark on the front, just under President Kennedy's neck. These 1972-S half dollars are composed of 40% silver. Their value is primarily tied to the fluctuating market price of silver. Generally, one of these coins is worth several dollars just for its silver content, with uncirculated or proof versions fetching a slightly higher premium.
As a fun tip for collectors, there is a well-known and valuable error to look for on the 1972-D half dollar. Some coins were accidentally struck without the designer's initials, "FG," on the reverse side below the eagle's left leg. This "No FG" variety is a rare find and can be worth a significant amount, often ranging from $20 to hundreds of dollars depending on its condition.
So, to find out what your coin is worth, first check for a mint mark! If it's a "D" or has no mark, it's likely worth 50 cents, but be sure to check for that "No FG" error. If you see an "S" mint mark, you've got a silver coin worth several dollars
