Hello! That's a great question about the 1972 Kennedy half dollar. The provided search results link to pages that discuss coin values, but they don't contain the specific pricing information themselves. Based on general numismatic knowledge, I can certainly help you figure out what your coin might be worth.
The value of a 1972 half dollar depends almost entirely on its condition and mint mark. For a standard, circulated coin that you might find in pocket change, it is typically worth its face value of 50 cents. These coins were made in very large quantities and are composed of a copper-nickel clad, meaning they don't have any silver content to give them additional melt value.
However, if your coin is in uncirculated, or mint, condition, it will be worth more to a collector. A typical uncirculated 1972 half dollar from either the Philadelphia (no mint mark) or Denver (D mint mark) mint might sell for a few dollars. The value increases with the quality, so a perfectly preserved specimen could be worth more. There are also proof coins from the San Francisco (S mint mark) mint, which were sold in collector sets and are generally worth a few dollars as well.
The key to finding a truly valuable 1972 half dollar is to look for rare errors or varieties. The most well-known for this year is the 1972-D "No FG" variety. On these rare coins, the designer's initials "FG" (for Frank Gasparro) are completely missing from the reverse side of the coin, to the right of the eagle's tail. If you have one of these, it could be worth a significant amount more than a regular coin, depending on its condition.
So, in short, a circulated 1972 half dollar is worth 50 cents, while an uncirculated one might be worth a few dollars. The main exception is the rare "No FG" error variety, which is much more valuable.
