The value of a 1974 Kennedy half-dollar is almost entirely dependent on its physical condition. For a coin that shows signs of wear from being used as currency, its value is generally just its face value of 50 cents. This is because the U.S. Mint produced a very large number of these coins for circulation, and they do not contain any silver, which is a key factor in the value of older U.S. coinage.
The worth of a 1974 half-dollar can increase significantly if it is in uncirculated or "Mint State" (MS) condition. As indicated by the provided context from professional coin resources like NGC, coins that were never circulated and remain in pristine condition are collectible. The value for these uncirculated coins is determined by a specific grade, with higher grades commanding higher prices. For example, a coin in a lower uncirculated grade might be worth a few dollars, while a coin in a superb state of preservation could be worth considerably more to a collector.
The 1974 half-dollars were produced at two mints: Philadelphia (which has no mint mark) and Denver (which has a "D" mint mark). Both are extremely common, so the mint mark does not typically add a premium unless the coin is in a very high grade. While the provided sources confirm that value is tied to condition, they do not contain specific price charts. For a precise valuation, the coin would need to be examined to determine its exact grade.
