Based on general numismatic knowledge, as the provided search result context did not contain specific pricing information, the value of a 1972 U.S. half dollar depends primarily on its mint mark and condition. These coins are part of the Kennedy Half Dollar series and were made from a copper-nickel clad composition, meaning they do not contain any silver and have no intrinsic melt value.
A standard 1972 half dollar found in circulation is typically worth only its face value of 50 cents. These coins were produced in large quantities by the Philadelphia Mint (no mint mark) and the Denver Mint (D mint mark), making them very common. Due to their wide circulation and lack of precious metal content, they generally do not carry a premium unless they are in exceptional condition.
For uncirculated coins that were never used as money, the value increases. A typical uncirculated 1972 or 1972-D half dollar might be worth between $2 and $5. The value can rise significantly for coins in pristine, high-grade condition as certified by a professional grading service, potentially reaching $30 or more for top-tier examples.
The San Francisco Mint also produced proof versions of the coin in 1972, which bear an "S" mint mark. These were made for collectors and feature a special mirror-like finish. A 1972-S proof half dollar is also quite common and is typically valued between $3 and $6.
It is also worth noting that rare error or variety coins can be much more valuable. For instance, some 1972-D half dollars are missing the "FG" initials of the designer, Frank Gasparro, on the reverse side of the coin. This "No FG" variety is a sought-after error that can be worth a significant premium, depending on its condition.
