Yes, a 1964 nickel without a mint mark was minted in Philadelphia. In 1964, the United States Mint produced a total of 1,024,672,000 Jefferson nickels, all of which were struck at the Philadelphia Mint. This was the only mint to produce nickels that year, and therefore, all 1964 nickels lack a mint mark.
The absence of a mint mark on a 1964 nickel can be confusing for collectors who are used to looking for mint marks as a way to identify where a coin was minted. However, the lack of a mint mark on a 1964 nickel is not uncommon or rare. In fact, all nickels minted at the Philadelphia Mint from 1942 to 1945 also lack mint marks due to the wartime effort during World War II.
Nickels minted at other mints, such as the Denver and San Francisco Mints, typically have a small “D” or “S” mint mark on the reverse (tails) side of the coin, below the Monticello building. Mint marks were used to identify which mint produced a particular coin and were also used to indicate variations in design or composition. For example, some wartime nickels produced during the same time as the 1964 nickel had a large “P” mint mark for Philadelphia because they were made of a different alloy due to the shortage of nickel during World War II.
In general, nickels without mint marks tend to be less valuable to collectors than those with mint marks because they are more common and easier to obtain. However, the value of any particular coin depends on a variety of factors, including its condition, rarity, and historical significance.
Some collectors may be interested in acquiring a complete set of Jefferson nickels, which would include a 1964 nickel without a mint mark. A complete set of Jefferson nickels includes one of every date and mint mark combination from 1938 to the present day. Collectors may also be interested in obtaining examples of coins in different conditions or from different production runs.
In general, the value of a 1964 nickel without a mint mark is relatively low. Most circulated examples are worth face value or only slightly more, while uncirculated examples may be worth a few dollars. However, there are always exceptions, and rare or unusual examples of a particular coin can command much higher prices.
In conclusion, a 1964 nickel without a mint mark was minted in Philadelphia and is not considered rare or valuable by most collectors. While it may be of interest to collectors who are assembling a complete set of Jefferson nickels or who are interested in the history of coin production in the United States, it is unlikely to fetch a high price on the collector’s market.
