The 1998-S Kennedy Half Dollar is worth anywhere from $5 in standard proof condition to over $1,000 for rare Silver Matte Finish specimens. Whether you found one in a collection or a mint set, its value depends heavily on the specific “S” mint variety and the metal composition.
| Coin Version | Approximate Value |
|---|---|
| 1998-S Clad Proof (Deep Cameo) | $5 – $15 |
| 1998-S Silver Proof (90% Silver) | $15 – $40 |
| 1998-S Silver Matte Finish (SMS) | $150 – $1,200+ |
Understanding the 1998-S Kennedy Half Dollar Origins
If you have a 1998 half dollar with an “S” mint mark, it was struck at the San Francisco Mint. Unlike the “P” or “D” coins you find in pocket change, these were specially made for collectors. By 1998, the United States Mint had perfected the art of creating high-contrast coins with frosted details and mirror-like backgrounds.
To accurately identify which version you have, many hobbyists use a top coin identifier app to zoom in on the mint mark and surface texture. Most 1998-S coins are Proofs, meaning they were struck twice with polished dies.
However, there is a legendary “ghost” in this series known as the Matte Finish silver half dollar. This particular coin was only sold in a special two-coin set alongside the Robert F. Kennedy Commemorative Silver Dollar. If you have the Matte version, you aren’t looking at pocket change—you’re looking at a high-value treasure. Using CoinKnow can help you distinguish between the shiny mirror proof and the satin-like matte finish.

Clad vs. Silver: Why the Metal Matters
In 1998, the San Francisco Mint produced two common types of proofs: the standard Copper-Nickel Clad and the 90% Silver version. Physically, they look very similar, but their market values differ based on precious metal content and collector demand.
The Clad version (composed of copper and nickel) is the most common. It was included in the standard 10-coin annual proof set. Because millions of these sets were produced, the supply is high, keeping the price relatively low. Even so, a perfectly preserved Clad proof is a beautiful addition to any collection.

The Silver version is made of 90% silver and 10% copper. These were sold in specialized “Silver Proof Sets.” Beyond their numismatic value, they carry “melt value” which fluctuates with the price of silver.

| Feature | Clad (S) | Silver (S) |

The Rare 1998-S Matte Finish Silver Half Dollar
The “Holy Grail” of 1998 Kennedy coins is the Matte Finish Silver Half Dollar. This coin does not have the shiny, reflective surface of a standard proof. Instead, it has a smooth, satin-like look, often described as “sandblasted” or “velvety.”
Only about 62,000 to 64,000 of these were ever produced, making it one of the lowest-mintage Kennedy Half Dollars in history. Because it was only available in the “1998 Kennedy Collectors Set,” many people don’t realize they have one if the set has been broken up.

If you suspect you have this rare variety, checking the 1998-S Matte Finish value guide is essential before selling. High-grade examples (SP69 or SP70) can fetch well over $500, with some auction records topping $1,200. Professionals often use CoinKnow to track these specific auction results in real-time.
Grading and Its Impact on Your Coin’s Price
When it comes to the 1998-S Kennedy Half Dollar value, the difference between a grade of 69 and 70 is massive. The Sheldon Scale, which goes from 1 to 70, determines a coin’s perfection. A 70 represents a “perfect” coin with no visible flaws even under 5x magnification.
Most 1998-S proofs come out of the Mint in near-perfect condition. Therefore, a grade of “69” is considered the baseline. These are generally worth just a few dollars over their silver or face value. However, “70” graded coins are highly sought after by registry set collectors who want the absolute best.

One of the best ways to eye-ball a grade is to look for “hairlines” or milk spots. These are small white cloudy patches that can form on silver proofs. Even a single milk spot can drop a coin from a $100 value down to $20. CoinKnow allows you to compare your coin against high-resolution images of graded examples to see where yours stands.
| Grade (PCGS/NGC) | Clad Proof Value | Silver Proof Value | Silver Matte Value |
|---|---|---|---|
| PR/MS 67 | $3 | $12 | $130 |
| PR/MS 69 | $12 | $25 | $180 |
| PR/MS 70 | $45 | $90 | $1,100+ |
How to Spot a 1998-S Kennedy Half Dollar in the Wild
While it is very rare to find an “S” mint coin in a simple roll of quarters or halves from the bank, it does happen. These are known as “proofs in circulation.” Usually, someone’s grandkid spends a collection, or a thief dumps a stolen set into a coin-counting machine.
When a proof coin circulates, it loses its mirror finish and develops scratches. At this point, the Clad 1998-S is usually only worth its face value ($0.50). However, the Silver 1998-S is still worth its weight in silver.
Checking the edge of the coin is the quickest test. If you see a solid silver edge without a copper “sandwich” line, you have found silver! Even in worn condition, a 90% silver half dollar from 1998 is a great find worth at least $10 based on current silver spot prices.

Collecting the 1998-S: Tips for Beginners
If you are just starting your coin collection with a 1998-S Kennedy Half Dollar, the most important rule is: Do not clean your coin. Many beginner collectors think that scrubbing a coin with soap or polish will make it “better,” but it actually destroys the collector value.
Instead, handle your 1998-S by its edges and keep it in a PVC-free plastic holder. This prevents oils from your fingers from staining the surface. If you have a Matte finish version, the surface is particularly sensitive to fingerprints.
Many new collectors find that using a digital tool helps keep their inventory organized. Apps like CoinKnow provide a simple way to track the value of your 1998-S over time, especially as silver prices fluctuate. Whether you have the common clad proof or the rare matte silver, knowing the history and rarity makes the hobby much more rewarding.

FAQ
Q: Why is there an “S” on my 1998 Half Dollar?
A: The “S” stands for the San Francisco Mint. In 1998, this mint only produced proof coins for collectors, not for general circulation. If you found one, it was likely removed from a special collector’s set.

Q: How can I tell if my 1998-S is silver or clad?
A: Look at the edge of the coin. If you see a brownish-copper stripe, it is Clad. If the edge is solid silver-white, it is 90% silver. You can also weigh it: Clad is 11.34g and Silver is 12.50g.
Q: Is the 1998-S Matte Finish worth $1,000?
A: Only if it is in perfect condition (Grade SP70). Most Matte 1998-S coins sell for between $150 and $250. It is a very rare coin that was only sold in the RFK commemorative set.
Q: Can I spend a 1998-S Half Dollar at the store?
A: Yes, it is legal tender for 50 cents. However, even the “cheapest” clad version is worth about $5 to a collector, so spending it would be a waste of money!
