The 1998 S Silver Roosevelt Dime is worth anywhere from $5 in typical proof condition to over $100 for high-grade Deep Cameo specimens. Finding one of these shiny treasures in your change is a rare treat, as they were never intended for general circulation but were sold in special sets for collectors.
Understanding the Rarity and Composition of the 1998 S Silver Dime
If you have stumbled upon a 1998 dime with an “S” mint mark, you have found something much more valuable than a standard ten-cent piece. Unlike the billions of dimes struck in Philadelphia and Denver that year, which are made of a copper-nickel clad composition, the 1998-S Silver Roosevelt Dime is composed of 90% silver and 10% copper. This gives the coin an intrinsic “melt value” that fluctuates with the silver market, but its numismatic value is often much higher.
Because these were minted specifically at the San Francisco Mint for inclusion in the annual Silver Proof Sets, they feature a brilliant, mirror-like finish and sharp details. If you are unsure whether the coin you found is the silver version or the standard clad proof, you can check the edge of the coin. A silver dime will have a solid silver-colored edge, while a clad dime will show a distinct copper stripe. To get an instant identification and valuation of your find, you can use a top coin identifier app which can help verify the specific variety you have in your hand.
Many everyday Americans discover these coins when they inherit a collection or find a “pantry stash” of old jars. When you use the CoinKnow app, you can quickly categorize these finds. Collectors value the 1998-S because it represents a modern era of high-quality minting techniques, often reaching the perfect grade of PR70.

Current Market Prices for 1998 S Silver Proof Dimes
The value of a 1998-S Silver Dime depends heavily on its “Proof” state and whether it has developed any toning or surface scratches. Most examples found today remain in Mint State because they were protected in plastic lenses. However, if a coin was removed from its set and handled, its value may drop toward its silver weight. On the other hand, a “Deep Cameo” (DCAM) specimen with a heavy frost on the portrait of FDR can command a premium.

For those curious about how this specific mint mark compares to others from the same year, the 1998 dime value for silver proofs is significantly higher than the common P or D versions found in your pocket. Even in a market where silver prices fluctuate, the demand for “S” mint coins remains steady among registry set collectors.

When comparing these prices to business-strike coins, you will notice that the 1998 dime price guide for MS grades shows that common circulation coins only gain significant value if they have rare errors or exceptionally high grades, whereas the silver “S” version starts with a high floor due to its metal content.
How to Identify a 1998 S Silver Dime vs Clad Proof
It is a common mistake for new hobbyists to confuse the 1998-S Silver Dime with the 1998-S Clad Proof Dime. Both were struck in San Francisco, and both have a beautiful mirror finish. However, the U.S. Mint produced both a “Base Metal” proof set and a “Silver” proof set in 1998. To tell them apart without a scale, look closely at the “third side” of the coin (the edge).
The silver version will be brilliantly white all the way around. The clad version will show a distinct orange/red copper line. If you are still unsure, a digital scale can provide the answer: a silver 1998-S Roosevelt dime weighs 2.50 grams, while a clad dime weighs 2.27 grams. Accurate identification is the first step in knowing if you have found a $10 coin or a $1 coin.

Utilizing the CoinKnow app can help you photograph the edge and surface of the coin to determine its likely composition. Many people find that their silver proof dimes have developed a beautiful “rainbow” toning over the years, which can actually increase the value to specialized collectors who enjoy unique colors on their silver coins.
Factors That Influence the Final Value of Your Dime
The most important factor is the condition, or “grade.” Professional grading services like PCGS or NGC use a 70-point scale. For a 1998-S Silver Roosevelt Dime, anything below a PR69 is considered average, as most were kept in protective cases. However, a PR70—the perfect grade—is elusive and rare. These perfect specimens are what serious investors look for in auctions.
Spotting errors is another way to see the value skyrocket. While extremely rare in the controlled environment of the San Francisco Mint, things like “Die Breaks” or “Double Dies” can occasionally occur. If you think you see a doubling of the letters or Roosevelt’s profile, it is worth getting an expert opinion. The CoinKnow mobile tool is a great way to start your research before paying for professional certification.

Lastly, the price of silver itself provides a “safety net” for the value. Even if the coin is scratched, it will always be worth at least its weight in 90% silver. As of the current market, this usually keeps the minimum value well above the face value of ten cents, making it a great find for any casual treasure hunter.

Q: Can I find a 1998 S Silver Dime in my pocket change?
