The value of a 1937 Buffalo Nickel is primarily determined by its condition, or grade, and its mint mark. Since over 100 million were produced across all mints, it is considered a common coin, and its value in circulated condition is relatively modest.
A heavily circulated 1937 nickel in "Good" condition is typically valued at approximately $1.00 to $2.00. For coins with more detail remaining, in "Fine" to "Extremely Fine" condition, the value generally ranges from $2.00 to $4.00.
The value increases significantly for uncirculated coins that have never been used in commerce and retain their original mint luster. A basic uncirculated 1937 Buffalo Nickel might be worth between $12 and $20. The value continues to climb with higher uncirculated grades; for instance, a coin graded MS65 (Gem Uncirculated) could be valued from $40 to $70, with the finest known examples fetching hundreds of dollars.
The mint mark, found on the reverse side below the image of the buffalo, also plays a crucial role. Coins were minted in Philadelphia (no mint mark), Denver (D), and San Francisco (S). While values are similar for circulated examples, the San Francisco issue typically carries a higher premium in uncirculated grades. A special and valuable error to look for is the 1937-D "3-Legged" variety, which is worth substantially more than a standard coin. For an accurate assessment of your coin's value, it is best to have it examined by a professional numismatist.
