The provided search result snippets from Bold Precious Metals and Greysheet indicate that these are resources for coin , but they do not contain the specific value of a 1971 half dollar. Based on general numismatic knowledge, the value of a 1971 Kennedy half dollar depends heavily on its condition and mint mark.
The year 1971 is significant as it was the first year the Kennedy half dollar was struck in a copper-nickel clad composition for circulation, meaning it contains no silver. Because of this and their high mintage numbers, 1971 half dollars in circulated condition are very common and are typically only worth their face value of 50 cents.
However, coins in pristine, uncirculated condition can be worth more to collectors. A standard 1971 half dollar from the Philadelphia (no mint mark) or Denver (D mint mark) mints might be worth a few dollars in a typical uncirculated grade. The value increases for coins in exceptionally high states of preservation.
There were also proof coins struck at the San Francisco mint (S mint mark) for collector sets. These proof versions, which have a mirror-like finish, are generally worth a few dollars. Certain rare error varieties of the 1971 half dollar exist and can command much higher prices, but these are not commonly found in circulation.
