The provided context is insufficient for determining the specific value of a 1964 half dollar coin, as it does not contain pricing data. However, based on general numismatic knowledge, a comprehensive answer can be provided.
The value of a 1964 Kennedy half dollar is primarily determined by two key factors: its silver content and its numismatic or collectible value, which is based on its physical condition or grade. Unlike later half dollars, the 1964 issue was the last one minted for circulation composed of 90% silver. This high silver content gives the coin a substantial base value, often referred to as its "melt value," which fluctuates daily with the spot price of silver. A standard 1964 Kennedy half dollar contains approximately 0.36 troy ounces of pure silver.
For coins that are circulated and show signs of wear, their value is typically tied closely to this silver melt value. As a result, even a common, worn 1964 half dollar is worth significantly more than its 50-cent face value. The exact amount will depend on the current market price for silver.
The coin's value can increase substantially if it is in uncirculated, or mint state, condition. Numismatists use a grading scale from 1 to 70 to describe a coin's condition, and higher grades command higher prices. An uncirculated 1964 Kennedy half dollar that retains its original mint luster and has few to no scratches or marks will carry a premium over its silver value. This premium grows with the quality, with exceptionally well-preserved examples fetching considerably higher prices from collectors.
Furthermore, there are special versions and varieties to consider. The U.S. Mint produced proof versions in 1964 specifically for collectors, which feature a distinct, mirror-like finish. These generally have a higher value than the standard business strike coins. Among the proof coins, a rare "Accented Hair" variety exists, which is highly sought after by collectors and carries a significant premium over all other versions of the 1964 half dollar. To get a precise valuation, a coin should be appraised by a professional coin dealer or grading service.
