The 1998-S Kennedy Half Dollar is worth anywhere from $5 in standard proof condition to over $3,500 for the rare matte finish version. Whether you found one in a relative’s collection or a storage locker, this coin carries a special history that makes it more valuable than its face value.

Identifying the Special 1998 Silver and Matte Half Dollars

If you are looking at a 1998 Kennedy Half Dollar with an “S” mint mark, you have found a coin produced at the San Francisco Mint. Unlike the 1998-P and 1998-D coins you might find in your pocket change, these were never intended for general circulation. If you want to identify your find quickly, using a top coin identifier app can help you distinguish between the different finishes and metal compositions.

In 1998, the Mint produced two primary types of “S” coins. The most common is the standard silver proof, which has a shiny, mirror-like surface. However, the real prize for collectors is the Matte Finish 1998-S. This coin was only available in the “Kennedy Collectors Set” alongside the Robert F. Kennedy commemorative silver dollar. It has a dull, satin-like appearance that looks more like a photograph than a traditional coin. If your coin looks “frosty” rather than “shiny,” it might be the high-value matte variety. You can easily track the latest market trends and verify these rarities with the CoinHix app.

How Much is Your 1998-S Half Dollar Worth Currently

The value of your 1998-S depends entirely on its condition and which specific version you hold. For a standard 1998-S Silver Proof, the price usually hovers between $15 and $30. These were struck in 90% silver and 10% copper, giving them inherent “melt value” as well as numismatic value. Even if the coin is slightly handled, the silver content ensures it remains worth much more than fifty cents.

The Matte Finish 1998-S is the true star of the year. Because only about 62,000 to 64,000 of these were produced, they are considered modern rarities. On the open market, a certified Matte Finish 1998-S in Mint State 69 can fetch between $150 and $300. If you are lucky enough to have a perfect MS 70 grade, the price can skyrocket into the thousands. Checking the 1998-P Kennedy Half Dollar price charts is a good way to compare how the circulation strikes stack up against these premium proof issues.

Coin Version	Mintage	Estimated Value (PR69/MS69)
1998-S Silver Proof	878,792	$25 – $45
1998-S Matte Finish (SMS)	62,100	$180 – $350
1998-S Matte Finish (MS70)	Low	$3,000+

Determining the Condition and Grade of 1998 Half Dollars

When searching for the 1998 Kennedy Half Dollar total market value, you will notice that the “Grade” is everything. Professional graders use a 1-to-70 scale. For “S” mint coins, which were sold in protective plastic cases from the Mint, most are expected to be in high grades like PR68 or PR69. Any scratch, fingerprint, or haze on the surface will immediately drop the price to the lower end of the spectrum.

If you have a 1998-S that has been removed from its original packaging and spent some time in a drawer, it might have “milk spots”—tiny white cloudy patches. While these are common on silver coins from this era, they can negatively affect the visual appeal for collectors. Using a tool like CoinHix allows you to see high-resolution examples of these grades so you can estimate where your coin sits before paying for professional grading services.

Why the 1998-S Kennedy Half Dollar is a Collector Favorite

The Kennedy Half Dollar series began in 1964 to honor President John F. Kennedy. By 1998, the series had undergone many changes in metal composition. The 1998-S Silver Proof was part of the annual Premier Silver Proof Set, which was a staple for collectors in the late 90s. This specific year remains popular because it represents one of the lowest mintage years for special-finish strike coins in the late 20th century.

Collectors often hunt for the “Matte Finish” 1998-S because it is part of a “short set” of special finish Kennedy halves. These coins have a soft, non-reflective gray surface that is highly distinguishable from the standard mirror coins. This uniqueness, combined with the low mintage of roughly 62,000 units, makes it one of the “keys” to a complete Kennedy collection. If you aren’t sure which version you have, simply open the CoinHix app and use the photo recognition feature to get an instant lead.

FAQ

Q: Is the 1998-S Half Dollar made of real silver?

A: Yes, the 1998-S Proof Half Dollar was produced in a silver version containing 90% silver and 10% copper. However, the Mint also produced standard clad proofs that year, so check the edge of the coin; a solid silver-colored edge usually indicates the silver version.

Q: How can I tell if my 1998-S is the rare Matte Finish?

A: The Matte Finish coin looks “sandblasted” or velvety and has no reflection. Regular proofs have a mirror-like background where you can see your reflection clearly. The Matte Finish was only sold in the Kennedy Collectors Set.

Q: Should I clean my 1998-S Kennedy silver coin to make it worth more?

A: No! Never clean your coins. Collectors prefer the original “patina” or “toning.” Cleaning a coin with chemicals or cloth creates micro-scratches that can destroy up to 90% of its collector value.

Q: Where can I sell my 1998-S Kennedy Half Dollar?

A: You can sell these coins to local coin shops, through reputable online auction sites, or at coin shows. For high-value Matte Finish versions, it is often best to have them graded by a service like PCGS or NGC first to maximize your profit.
