Based on the provided information and general numismatic knowledge, the value of a 1972 Kennedy half dollar depends heavily on its condition, mint mark, and whether it has any rare errors. For most of these coins found in circulation, the value is simply their face value of 50 cents. These coins are made from a copper-nickel clad composition and contain no silver, so they do not have any intrinsic precious metal value.
The U.S. Mint produced 1972 half dollars at two main facilities for general circulation: Philadelphia (which has no mint mark) and Denver (which has a "D" mint mark on the obverse). In typical circulated condition, both the 1972 and 1972-D half dollars are worth face value. However, coins in uncirculated, like-new condition are worth a premium to collectors, typically fetching a few dollars. The value can rise significantly for coins that are professionally graded and certified in the highest states of preservation.
Additionally, certain rare die varieties can be worth much more. As hinted by collecting resources that discuss "cherry-picking," a notable error for this year is the 1972-D "No FG" variety. On this specific coin, the designer's initials, "FG" (for Frank Gasparro), are completely missing from the reverse side, just under the eagle's tail. This error is highly sought after by collectors and can be worth anywhere from $20 to over $500, depending on its specific condition and grade. Therefore, while most 1972 half dollars are common, it is worth checking the reverse side for this specific valuable error.
