1998-S Silver Kennedy Half Dollar Value and Price Guide
The 1998-S Silver Kennedy Half Dollar is worth anywhere from $15 in standard proof condition to over $150 for top-tier specimens. While most found in collections are common, deep cameo versions can fetch a significant premium among enthusiasts.
| Grade / Condition | Estimated Value |

| PR 69 Deep Cameo | $25 – $40 |
| PR 70 Deep Cameo | $120 – $185+ |
What Makes the 1998-S Silver Kennedy Half Dollar Special?
If you have stumbled upon a 1998 Kennedy Half Dollar, the first thing you need to determine is its metal composition. Unlike the standard copper-nickel clad versions minted for circulation in Philadelphia and Denver, the “S” mint mark signifies it was struck at the San Francisco Mint.
During 1998, the Mint produced two distinct types of “S” proof coins: a standard clad version and a special silver version. The 1998-S Silver Kennedy Half Dollar is struck in 90% silver and 10% copper, a homage to the original 1964 composition.
If you aren’t sure which one you have, the easiest way to identify it is by looking at the edge of the coin. A silver coin will show a solid bright white edge, whereas a clad coin will show a distinct copper leaf or “sandwich” line.

Composition and Technical Specifications
Understanding the physical makeup of your 1998-S Silver Kennedy Half Dollar is crucial for valuation. Because it contains precious metal, the coin has a “floor” value based on the current spot price of silver. However, because it is a proof coin, its numismatic value is almost always higher than its raw silver content.
The 1998 silver proof differs significantly from its circulating counterparts from Philadelphia, as seen in the 1998-P Kennedy Half Dollar price data. While the P and D mint marks are common business strikes, the S silver proof is a specialized collector’s item.
| Feature | Specification |
|---|---|
| Composition | 90% Silver, 10% Copper |
| Silver Weight | 0.36169 troy oz |
| Diameter | 30.6 mm |
| Mintage | 878,792 |
Grading and the “Deep Cameo” Factor
When discussing the value of a 1998-S Silver Kennedy Half Dollar, “Deep Cameo” (DCAM) is a term you will hear often. This refers to the visual contrast between the frosted details (like JFK’s portrait) and the mirror-like background fields.
Because these were struck for collectors, most 1998-S coins are in excellent condition. However, there is a massive price gap between a PR69 (nearly perfect) and a PR70 (absolute perfection). A PR70 specimen is extremely rare and highly sought after by registry set collectors.
If you find a coin that looks “brighter” or “shinier” than usual, it is worth checking its grade. Use the CoinKnow app to compare your coin against high-resolution images of graded specimens. A small scratch invisible to the naked eye can drop the value significantly.

The Rare Matte Finish Variant
While the standard 1998-S Silver Proof is common, there is a “holy grail” for this year: the 1998-S Matte Finish Silver Kennedy Half Dollar. This coin was only available in the “Robert F. Kennedy Commemorative Silver Set.”
Unlike the shiny, mirror-like proof coins, the Matte Finish version has a satin-like, grainy appearance. It was struck using specially prepared dies and planchets. Because the mintage was limited to approximately 62,000 units, this specific variant is worth much more than the standard proof.
| Finish Type | Estimated Value (Grade 69/70) |
|---|---|
| Standard Silver Proof | $35 – $150 |
| Matte Finish Silver | $180 – $500+ |
Determining if Your Coin is Worth Grading
A common question among everyday Americans is: “Should I send my coin to PCGS or NGC?” Grading costs roughly $30-$50 per coin when shipping and handling are included. For a standard 1998-S Silver Kennedy Half Dollar, it only makes sense to grade it if you are confident it will hit a PR70 grade.
If the coin has been handled without gloves, has fingerprints, or shows even tiny hairline scratches, it will likely grade as a PR68 or PR69. In these grades, the cost of grading often exceeds the value of the coin.
However, if you have a Matte Finish variant, professional grading is almost always recommended to authenticate the coin and protect its value. Digital tools like CoinKnow can help you perform a preliminary assessment before you spend money on professional services.
Market Trends and Long-term Investment
The market for modern silver proofs is generally stable. Because the 1998-S Silver Kennedy Half Dollar is part of the long-running Kennedy Half Dollar series, there is constant demand from “completest” collectors who aim to own every date and mint mark.
While silver bullion prices fluctuate, the numismatic premium on these coins tends to hold steady. As more of these coins are removed from their original mint packaging and potentially damaged or toned over time, the value of “Blast White” high-grade specimens continues to climb slowly.
Investors often look for 1990s silver proofs because they have lower mintages than the silver proofs of the 2000s and 2010s. The 1998-S remains a solid entry-point for new collectors looking to own a piece of silver history without spending thousands of dollars.
| Year / Mint | Mintage (Silver) | Relative Rarity |
|---|---|---|
| 1998-S Silver | ~878k | Moderate |
| 1998-S Matte | ~62k | Very Rare |
How to Safely Store Your Half Dollar
If you find a 1998-S silver coin, preservation is key to maintaining its value. Silver is prone to toning—a chemical reaction with sulfur in the air that turns the coin yellow, blue, or black. While some collectors like “rainbow toning,” most prefer the original white luster for modern proofs.
Avoid keeping your coins in PVC-laden plastic flips, as the chemicals can “melt” onto the surface of the coin, creating a green goo that destroys value. Instead, use PVC-free Mylar flips or air-tight capsules.
If your coin is currently in a 1998 Silver Proof Set lens, it is often best to keep it there. Original Government Packaging (OGP) is highly respected by many buyers and ensures the coin’s origin is verified.
FAQ
Q: Is every 1998 Kennedy Half Dollar silver?
A: No. Only the coins minted in San Francisco (S mint mark) that were specifically designated for Silver Proof Sets are 90% silver. The ones you find in common pocket change are made of copper and nickel.
Q: How can I tell the difference between a silver proof and a clad proof?
A: Check the edge of the coin. A silver proof will have a solid silver/white edge. A clad proof will show a brown/copper stripe along the middle of the edge. Additionally, the silver coin is heavier (12.50 grams vs 11.34 grams).
Q: Where can I sell my 1998-S Silver Kennedy Half Dollar?
A: You can sell to local coin shops, through online auctions like eBay, or to reputable online bullion and numismatic dealers. Professional grading via PCGS or NGC can help you get a higher price on eBay.
Q: What is the silver melt value of this coin?
