Based on general numismatic knowledge, as the provided context did not contain specific pricing information, the value of a 1964 Kennedy half dollar depends on several factors. Its primary value for most examples is derived from its silver content. The 1964 half dollar is composed of 90% silver and contains approximately 0.36169 troy ounces of the precious metal. Therefore, its base value, or melt value, fluctuates daily with the market spot price of silver.
Beyond its intrinsic silver worth, the coin can carry a numismatic premium based on its condition and origin. Coins that are heavily worn from circulation are typically worth only their melt value. However, coins in uncirculated, or Mint State, condition are worth more to collectors. The exact premium depends on the grade; a higher grade signifies a better-preserved coin and commands a higher price.
There are a few different versions of the 1964 half dollar. Business strikes intended for circulation were produced at the Philadelphia mint (no mint mark) and the Denver mint ('D' mint mark). Additionally, the Philadelphia mint produced special proof coins for collectors, which feature a mirror-like finish. Among these proof coins, a desirable and more valuable "Accented Hair" variety exists, which is sought after by collectors.
In summary, a common, circulated 1964 Kennedy half dollar is valued based on its silver content. The value increases for uncirculated examples and can be significantly higher for top-grade specimens or rare varieties. For a precise appraisal, it is always recommended to have the specific coin evaluated by a reputable coin dealer or professional grading service.
