The provided search results do not contain specific information regarding the value of a 1964 nickel. Therefore, this answer is based on general numismatic knowledge on the topic.
A 1964 Jefferson nickel is an extremely common coin, and in most cases, it is worth its face value of five cents. The United States Mint produced a very high number of these coins, with over one billion struck at the Philadelphia mint and over 1.7 billion at the Denver mint (identified by a "D" mint mark on the reverse). Due to this massive mintage, a 1964 nickel found in circulation will typically show signs of wear and will not carry any premium value for collectors.
The value of a 1964 nickel increases only if it is in uncirculated, mint-state condition. A standard uncirculated example that has no wear and retains its original mint luster might be worth between 25 cents and one dollar. For a coin to be worth more, it would need to be in pristine, gem condition, professionally graded at a very high level, such as MS-65 or above. In such cases, the value could rise to several dollars.
It is also important to note the existence of rare varieties or error coins, which can be significantly more valuable. For the 1964 nickel, a well-known variety is the "Special Mint Set" or SMS version. These coins were struck with a special satin-like finish and are much sharper in detail than regular circulation strikes. True 1964 SMS nickels are quite rare and valuable, but they can be difficult to authenticate without professional expertise. Unless the coin is a high-grade uncirculated example or a confirmed rare variety, its value remains at five cents.
