Based on expert numismatic knowledge, I can certainly help you determine the value of your coin. The provided search context was not useful as it didn't contain specific pricing information, but understanding the 1972 half dollar is straightforward.
It's a fantastic question, and one that often comes up because of the coin's history! The most important factor in determining the value of your 1972 half dollar is realizing that the vast majority of them contain no silver at all. The half dollars made for everyday circulation that year, struck at the Philadelphia (no mint mark) and Denver ("D" mint mark) mints, are made of a copper-nickel clad composition. If you found one of these in your pocket change, it is almost certainly worth only its face value of 50 cents.
However, you're right to ask about a "silver" version, because the U.S. Mint did produce special collector coins that year that contain precious metal. To find out if you have one of these more valuable coins, you need to look for an "S" mint mark on the front (obverse) of the coin, just below the neck of President Kennedy. These special half dollars were struck at the San Francisco Mint and were sold to collectors in Proof and Uncirculated sets.
If you've confirmed you have a 1972-S half dollar, then you're holding a coin made of 40% silver. Its base value is tied directly to the current market price of silver, which typically means it's worth a few dollars just for its metal content. Beyond that, it has collectible value. A 1972-S in its original brilliant uncirculated or proof condition is quite common but can sell to a collector for anywhere between $4 and $10, depending on its specific grade and eye appeal. So, before you spend it, be sure to check for that all-important "S" mint mark
