The 1940-S Jefferson Nickel is worth anywhere from $0.15 in worn condition to over $1,500 in high-grade mint state. Finding one of these in your pocket change is an exciting moment for any casual collector, as it represents a piece of American history from the early years of this iconic coin series.

History and Significance of the 1940-S Jefferson Nickel

The Jefferson Nickel was first introduced in 1938, replacing the famous Buffalo Nickel. By 1940, the design was still relatively new to the American public. The “S” mint mark on the reverse indicates that this specific coin was struck at the San Francisco Mint. During this era, San Francisco typically produced fewer coins than the Philadelphia or Denver mints, which often makes “S” marked coins more desirable to collectors. If you are unsure whether your old pocket change holds hidden treasure, using a top coin identifier app can help you instantly recognize the mint mark and variety of your finds.

When you look at a 1940-S Nickel, you are seeing Felix Schlag’s classic design of Thomas Jefferson on the obverse and his Virginia estate, Monticello, on the reverse. Because these coins were made of a copper-nickel alloy (75% copper, 25% nickel) rather than silver, many people assume they aren’t worth much. However, the 1940-S is a key date for those trying to complete a full set of Jefferson Nickels. For an accurate assessment of your collection, it is helpful to use tools like CoinKnow to keep track of your inventory and current market trends.

Understanding the Value of Your 1940-S Jefferson Nickel

The value of a 1940-S Jefferson Nickel depends almost entirely on its physical condition, also known as its “grade.” Most coins found in jars or old piggy banks are considered “circulated,” meaning they have scratches, smoothed-out details, and a duller finish. These are generally worth between $0.15 and $1.00. However, if the coin looks like it just came from the bank in 1940—with a bright luster and sharp details on Jefferson’s hair and the pillars of Monticello—the value jumps significantly.

Serious collectors look for “Full Steps” (FS) on the reverse. This refers to the steps leading up to Monticello. In most strikes, these steps are blurry or merged. If your coin has five or six clearly defined, uninterrupted steps, it is considered a premium specimen. You can check the latest 1940-S Jefferson Nickel mint state prices to see how much a high-quality “Full Steps” version can fetch at auction. Some of these pristine coins have sold for thousands of dollars because they are so rare in such perfect condition.

Condition / Grade	Estimated Value (USD)
Good (G-4) to Fine (F-12)	$0.15 – $0.35
Extremely Fine (XF-45)	$0.50 – $1.50
About Uncirculated (AU-50+)	$2.00 – $5.00
Mint State (MS-63)	$15.00 – $25.00
Mint State (MS-66+)	$100.00 – $450.00
Mint State (MS-67 Full Steps)	$1,500.00+

How to Identify the Mint Mark and Rare Variations

To find the mint mark on a 1940 Jefferson Nickel, look at the reverse side (the back). To the right of the Monticello building, next to the rim, you will see a small “S” for San Francisco or a “D” for Denver. If there is no letter at all, it was minted in Philadelphia. The “S” mint mark is particularly interesting because San Francisco produced only about 39.6 million nickels that year, which is significantly lower than Philadelphia’s 176 million.

There are also rare “error” versions of the 1940-S that can increase the value. Some collectors search for “re-punched mint marks” (RPM), where the “S” appears to have a shadow or looks like it was stamped twice. These tiny details are often missed by the naked eye but can be easily spotted using a high-resolution identification tool like CoinKnow. For more detailed statistics, you can examine the current market value for 1940 nickels to see how these errors impact the final price.

Tips for Preserving and Selling Your 1940-S Nickel

If you find a 1940-S Nickel that looks shiny and new, the most important rule is: Do Not Clean It. Many beginners think that scrubbing a coin with soap or polish will make it more valuable. In reality, cleaning a coin leaves microscopic scratches that professional graders can easily spot, and it can reduce the coin’s value by up to 90%. Instead, hold the coin only by its edges and place it in a protective PVC-free flip or a small plastic bag.

When you are ready to determine if your coin is worth the effort of professional grading, use CoinKnow to compare your coin’s image with graded examples. Selling your coin can be done through local coin shops, online auction sites, or specialized numismatic forums. For coins estimated to be worth over $100, getting them certified by a service like PCGS or NGC is often worth the investment, as it guarantees the authenticity and grade to potential buyers.

Frequently Asked Questions

Q: Is the 1940-S Jefferson Nickel made of silver?

A: No, Jefferson Nickels minted in 1940 are composed of 75% copper and 25% nickel. Silver was only used in nickels from mid-1942 through 1945, known as “War Nickels,” to save nickel for the war effort.

Q: What is the highest price ever paid for a 1940-S Nickel?

A: A pristine 1940-S Jefferson Nickel graded MS67 with Full Steps has sold for over $5,000 at professional auctions. However, these specimens are incredibly rare and usually held in private collections.

Q: How can I tell if my 1940-S Nickel is a “Full Steps” version?

A: Look at the steps on the Monticello building on the back of the coin. If you can see at least five distinct, horizontal lines representing the stairs without any interruptions from scratches or weak striking, you may have a “Full Steps” coin.

Q: Where is the best place to sell my old nickels?

A: For common circulated coins, a local coin shop is easiest. For rare, high-grade coins or error varieties, online auctions like eBay or Heritage Auctions generally provide the best exposure to serious collectors willing to pay top dollar.
