The provided search result information does not contain specific price data for the 1964 Kennedy half dollar. However, as an expert, I can provide a comprehensive overview of its value based on established numismatic principles.
The value of a 1964 Kennedy half dollar is primarily determined by two factors: its silver content and its condition, or grade. This particular year is unique and highly sought after because it was the only year the circulating Kennedy half dollar was struck with a 90% silver composition. All subsequent years, from 1965 to 1970, contained only 40% silver, and later versions contain no silver at all.
For a common, circulated 1964 Kennedy half dollar found in pocket change, its base value is its "melt value," which is tied directly to the current spot price of silver. The coin contains approximately 0.36 troy ounces of pure silver. This means its value will typically fluctuate between $9 and $12, depending on the day's market. Most coins from 1964 that show signs of wear will be worth this intrinsic silver value.
If the coin is in uncirculated, or Mint State, condition, it will carry a premium well above its silver melt value. The price for an uncirculated coin can range from around $15 to $30 or more, with the value increasing significantly for coins in near-perfect condition. There are also proof versions of the coin, made for collectors with a special mirrored finish, which also command higher prices. Certain rare varieties, such as the "Accented Hair" proof variety, are worth substantially more, often valued in the hundreds of dollars or higher depending on their certified grade. For a precise valuation, it is always recommended to have the coin appraised by a reputable coin dealer.
