The 1978-S Jefferson Nickel is worth anywhere from $1 in typical circulated condition to over $15 for high-grade Deep Cameo specimens. While these coins were minted specifically for collectors, finding one in your pocket change is a thrilling discovery that connects you to the history of the San Francisco Mint.

Condition / Grade	Estimated Value
PR 65 (Standard Proof)	$1.50 – $3.00
PR 67 Deep Cameo	$5.00 – $8.00
PR 69 Deep Cameo	$15.00 – $25.00
PR 70 Deep Cameo (Perfect)	$150.00+

Identifying the 1978-S Jefferson Nickel

If you have found a nickel from 1978 that looks exceptionally shiny, you likely have the “S” mint mark version. Unlike the coins minted in Philadelphia or Denver for general circulation, the 1978-S was struck at the San Francisco Mint. These were produced as “Proof” coins, meaning they were made using specialized dies and polished blanks to create a mirror-like finish.

If you aren’t sure whether your coin is a standard business strike or a proof, using a top coin identifier app can help you distinguish between the different minting processes. The “S” mint mark is located on the obverse (front) of the coin, specifically to the right of Thomas Jefferson’s ponytail, just above the date.

Most 1978-S nickels were sold originally in United States Proof Sets. Over the years, many of these sets have been broken open, and the individual coins have occasionally found their way into spare change bowls or vending machines. While a circulated 1978-S loses much of its collector premium, a “Deep Cameo” version—where the portrait looks frosted against a mirror background—remains highly desirable. To get an instant read on your find, the CoinKnow app can provide high-resolution comparisons to help you spot these details.

The Importance of the “S” Mint Mark and Proof Finish

In 1978, the San Francisco Mint focused exclusively on producing proof coinage for collectors. This means there are no 1978-S nickels intended for daily commerce. A total of 3,127,781 of these coins were produced. While three million might sound like a lot, it is a tiny fraction of the hundreds of millions of nickels struck in Philadelphia (no mint mark) and Denver (D mint mark) that same year.

Collectors value proof coins based on their “Cameo” effect. A standard proof has a shiny surface, but a “Cameo” (CAM) or “Deep Cameo” (DCAM) coin features a sharp contrast. The portrait of Jefferson and the Monticello building will appear chalky or white, while the fields (the flat background) look like a dark, polished mirror.

When evaluating your collection, checking the 1978 Jefferson Nickel value by grade is essential for understanding the market. Even a small scratch visible only under magnification can drop a coin from a $50 value down to a $2 value. Professional grading services like PCGS or NGC are often used for the highest quality coins, but for everyday enthusiasts, CoinKnow offers a great way to estimate the grade at home.

Mint Mark	Strike Type	Mintage
None (Philadelphia)	Business Strike	391,308,000
D (Denver)	Business Strike	313,092,160
S (San Francisco)	Proof	3,127,781

Determining the Value of a 1978-S Jefferson Nickel

Values for the 1978-S are heavily dependent on the “technical grade.” Because these were handled with care by the mint, most survivors are in decent shape. However, “Proof 70” coins—those that are absolutely perfect under 5x magnification—are extremely rare and can fetch hundreds of dollars at auction.

For most people, the coin they find will be in the Proof 63 to Proof 67 range. If the coin has been touched by bare hands, the oils from the skin can cause “clouding” or “toning” over time, which often reduces the value. If you notice rainbow colors on your nickel, don’t clean it! Some collectors actually pay a premium for attractive natural toning.

To see how current market trends affect your specific coin, you can research the current average prices for 1978 nickels. Keeping an eye on recent eBay “Sold” listings is another great way to see what people are actually paying. Often, the CoinKnow app will aggregate this data for you, saving you the time of manual searching.

Error Coins and Varieties to Look For

While 1978 wasn’t a major year for famous errors like the 1955 doubled die penny, there are still manufacturing defects that can make a 1978-S Jefferson Nickel worth significantly more. Proof errors are especially rare because the quality control at the San Francisco Mint is much stricter than at other locations.

Look for “Double Dies,” where the lettering or the date appears to have a slight shadow or secondary image. Another common error is a “Repunched Mint Mark” (RPM), though these were becoming less common by the late 70s. You should also keep an eye out for “strike-through” errors, where a piece of debris got between the die and the coin blank, leaving a permanent indention in the metal.

If you suspect you have an error, use a jeweler’s loupe or a high-quality macro camera lens. Errors are highly localized, and sometimes the difference between a rare error and a common scratch is microscopic. The CoinKnow tool can help you identify common error patterns recognized by the numismatic community.

Potential Error Type	Description	Estimated Value
Double Die Obverse	Doubling on ‘Liberty’ or Date	$20 – $100+
Off-Center Strike	Design is not centered	$50 – $200
Proof Strike-Thru	Foreign object pressed into coin	$15 – $50

Why the 1978-S Jefferson Nickel Remains Popular

The late 1970s was a transitional period for the U.S. Mint, and the Jefferson Nickel series is a favorite for budget-conscious collectors. Because the 1978-S is affordable, it is often the first “S-mint” coin a young collector adds to their album. Its accessibility makes it a staple of the hobby.

Furthermore, the 1978-S serves as a great example of the “Full Steps” (FS) detail. While “Full Steps” is a designation usually reserved for business strikes (P and D), collectors still look for sharp, crisp lines on the steps of Monticello on the reverse of the proof versions. A coin with mushy or blurred steps will always be worth less than one with a razor-sharp strike.

Whether you are building a complete “Dansco” album of Jefferson Nickels or you just happened to find a shiny coin in your change, the 1978-S is a piece of American history. It represents the craftsmanship of the San Francisco Mint and the enduring legacy of one of America’s most famous Founding Fathers.

FAQ

Q: Can I find a 1978-S nickel in circulation?

A: While it is rare, it is possible. These coins were originally sold in proof sets for collectors, but occasionally they are spent by people who don’t realize their value. If you find a very shiny 1978 nickel with an “S” mark, it was likely pulled from a set.

Q: What is the highest price ever paid for a 1978-S Nickel?

A: Rare “Perfect” specimens graded PR70 Deep Cameo by PCGS have sold for over $300 in past auctions. However, the average collector-grade coin usually sells for between $1 and $5.

Q: Should I clean my 1978-S Jefferson Nickel to make it worth more?

A: No! You should never clean collectible coins. Cleaning creates microscopic scratches that ruin the “mint luster” or the mirror finish of a proof. A cleaned coin will almost always be worth significantly less than an uncleaned one, even if the uncleaned one looks “dirty.”

Q: Is the 1978-S nickel made of silver?

A: No. By 1978, all Jefferson Nickels were made of a cupro-nickel alloy (75% copper and 25% nickel). The only Jefferson Nickels that contain silver are the “War Nickels” minted from 1942 to 1945.
