The 1999-S Jefferson Nickel is worth anywhere from $3 in typical Proof condition to over $50 for high-grade specimens with exceptional clarity. While most nickels from 1999 you find in your pocket change are common, the “S” mint mark signifies a special production that catches the eye of many Americans.
Understanding the Unique Status of the 1999 S Jefferson Nickel
If you have discovered a nickel dated 1999 with a small “S” next to the date, you aren’t looking at an ordinary coin meant for a vending machine. The San Francisco Mint produced these exclusively for collectors as part of annual Proof Sets. Unlike the billions of nickels struck in Philadelphia and Denver for daily commerce, these were struck twice using polished dies and specially prepared blanks. This process creates a mirror-like background and frosted details that make the portrait of Thomas Jefferson stand out beautifully.
Because these was never intended to be spent, finding one in your spare change is quite rare. Usually, it means someone broke open a collector set to spend the money. To get an instant valuation of any unusual coin you find, using the CoinKnow app is a great way to verify the mint mark and strike type.

Most 1999-S nickels are classified as “Deep Cameo.” This means the contrast between the shiny field and the matte images is intense. While they are beautiful, they are also quite common in the collector market because millions of sets were sold. However, perfection is where the real money lies. A nickel that has been protected in its original plastic case will always command a higher premium than one that has been rattling around in a piggy bank.
Detailed Price Guide and Grading Tiers for 1999 S Nickels
When determining value, the most important factor is the condition, or “grade.” Since 1999-S nickels are Proof coins, they are graded on a scale from PR1 to PR70. Most examples found today sit comfortably at PR67 or PR68. To reach the higher price brackets, the coin must be flawless under magnification, showing no scratches, fingerprints, or “milk spots” which can sometimes develop on modern coins.
Evaluating the value of a 1999 nickel depends heavily on these surface conditions. If you have a version from the Philadelphia mint, you might want to look into specific 1999-P Jefferson nickel price trends to see how they compare to the San Francisco proof versions. Generally, the “S” mint mark is more desirable to casual collectors because of its aesthetic appeal.
Below is a breakdown of what you can expect to receive for a 1999-S Jefferson Nickel based on its professional grade:
| Condition / Grade | Estimated Market Value |
|---|---|
| PR 65 (Typical Proof) | $3.00 – $5.00 |
| PR 68 Deep Cameo | $7.00 – $12.00 |
| PR 69 Deep Cameo | $15.00 – $22.00 |
| PR 70 Deep Cameo (Perfect) | $45.00 – $85.00 |
Identifying 1999 Jefferson Nickel Variations and Mint Marks
To know if your nickel is actually the valuable “S” version, you need to look at the right side of Thomas Jefferson’s portrait. You will see the year 1999, and directly below that will be a single letter. A “P” indicates Philadelphia, a “D” indicates Denver, and an “S” indicates San Francisco. The San Francisco version is the only one produced with the high-gloss finish.
If you find a 1999-P or 1999-D, don’t get discouraged. While they are usually only worth five cents if they have been circulated, uncirculated rolls can still be worth more than face value to the right buyer. Collectors often look for “Full Steps” on the back of the coin, which refers to the steps leading up to Monticello. If all six steps are clearly visible and not blurred together, the value can jump significantly for the P and D mintages.
For everyday users, the CoinKnow app remains a top-tier resource for identifying these subtle differences. Simply snapping a photo can tell you whether you have a common pocket coin or a proof that escaped from a collection. Knowledge is power in the hobby of numismatics, and even a modern 1999 nickel can be a gateway into a fascinating world of history and profit.
Common Errors to Look for in 1999 Coinage
While the 1999-S is a proof coin and subject to strict quality control, errors do occasionally slip through. Mint errors can turn a $5 coin into a $100 coin overnight. Some of the most common errors for nickels from this era include off-center strikes, where the design is pushed to one side, or “clipped planchets,” where the coin looks like a bite was taken out of it.
Another interesting phenomenon is the “Die Clash,” where the images from the front and back of the coin are accidentally pressed into each other’s dies. If you see the faint outline of Monticello behind Jefferson’s head, you might have a valuable error. Always handle your coins by the edges to avoid leaving fingerprints, as oils from your skin can degrade the value of a proof nickel over time.
Using CoinKnow can assist you in comparing your coin against known error databases. Most 1999 nickels you find will be standard, but the thrill of the hunt is finding that one-in-a-million mistake. If you think you’ve found an error, it is often worth having it looked at by a local coin shop or a professional grading service like PCGS or NGC.
FAQ about 1999-S Nickels
Q: Can I find a 1999-S Jefferson Nickel in my change?
A: It is rare but possible. These were only sold in sets to collectors, so if you find one in circulation, it was likely spent by someone who didn’t realize its value or was part of a stolen collection. They will look much shinier than a regular nickel.
Q: What makes the 1999-S more valuable than a 1999-D?
A: The “S” mint mark denotes a Proof coin. These were made with higher quality standards and in much lower quantities (roughly 3.3 million) compared to the hundreds of millions of “D” nickels made for general use.
Q: How can I tell if my 1999 nickel is a “Deep Cameo”?
A: A Deep Cameo (DCAM) coin has a very strong contrast. The background (field) should look like a dark mirror, while the raised parts (the portrait and building) should look white and frosty. Most 1999-S nickels are DCAM by default.
Q: Is it worth getting a 1999-S Nickel professionally graded?
A: Only if it appears to be absolutely perfect. A PR70 (perfect) grade can be worth $50 or more, but the cost of grading (often $20-$40) might be higher than the value of the coin if it only earns a PR68 or PR69 grade.
