Hello there! That's a great question about the 1971 half dollar. While the provided links seem like they would be very helpful, the text itself doesn't contain the specific value information. So, I'll draw on my general knowledge to give you a comprehensive answer.
The value of a 1971 Kennedy half dollar depends almost entirely on its condition and mint mark. For most of these coins that you might find in circulation or old coin jars, they are worth their face value of 50 cents. This is because 1971 was the first year these half dollars were made from a copper-nickel clad composition, meaning they contain no silver. Earlier half dollars had silver content, which gives them a higher base value.
However, if the coin is in uncirculated, like-new condition, it can be worth more to a collector. A typical uncirculated 1971 or 1971-D (for the Denver mint) might fetch a few dollars. The value increases for coins in pristine, high-grade condition that have been professionally graded.
There is also the 1971-S half dollar, which was minted in San Francisco. These were not made for general circulation but were sold to collectors as part of proof sets. They have a special mirror-like finish. A 1971-S proof half dollar is typically worth around $3 to $5, with higher values for coins in exceptional condition.
In short, a circulated 1971 half dollar is worth 50 cents. An uncirculated one is worth a few dollars, and a special proof version (with the 'S' mint mark) is worth a bit more.
