2018-S Roosevelt Dime Value: Is Your Silver Proof Extra Rare?
The 2018-S Roosevelt Dime is worth anywhere from $5 in standard proof condition to over $35 for high-grade Silver Proof specimens. While you won’t find these in your pocket change, they are prized by collectors for their mirror-like finish and specific precious metal content.
| Condition / Grade | Estimated Value |
|---|---|
| PR69 Clad Proof | $5 – $7 |
| PR70 Clad Proof (Deep Cameo) | $15 – $20 |
| PR69 Silver Proof (90% Silver) | $12 – $15 |
| PR70 Silver Proof (90% Silver) | $35+ |
Understanding the 2018-S Roosevelt Dime Production
If you have stumbled upon a dime with an “S” mint mark dated 2018, you have found a coin that was never intended for general circulation. These coins were minted specifically at the San Francisco Mint for collectors and sold in official United States Mint sets. If you want to identify your find quickly, using a free coin identifier app can help you distinguish between the different finishes.
The 2018-S Roosevelt Dime comes in two distinct varieties: the Copper-Nickel Clad version and the Silver Proof version. The clad version consists of a copper core with outer layers of nickel, while the silver version is composed of 90% silver and 10% copper.
Because these were handled with care and sold in protective packaging, they usually maintain a high level of brilliance. However, if a coin is removed from its set and spent, it becomes “impaired,” and its value drops significantly. Many collectors use CoinKnow to track the market fluctuations of these proof sets to decide when to buy or sell.
Differentiating Between Clad and Silver Proofs
Identifying whether your 2018-S dime is clad or silver is the most important factor in determining its worth. To the untrained eye, they look nearly identical. However, the weight and the “edge test” are the most reliable ways to tell them apart.
A silver dime will have a solid silver-colored edge, whereas a clad dime will show a distinct copper stripe along the side. Furthermore, the silver variety is part of the 2018 Silver Proof Set, which was the last year the U.S. Mint used the traditional 90% silver composition before switching to 99.9% fine silver in 2019. This historical transition adds a layer of interest for numismatists.
Checking the current market trends for high-grade 2018 dimes can show you how much of a premium the silver versions currently command. Collectors often use CoinKnow to scan their coins and verify the metal composition based on the specific set weights.
| Feature | 2018-S Clad Proof | 2018-S Silver Proof |
|---|---|---|
| Composition | 75% Copper / 25% Nickel | 90% Silver / 10% Copper |
| Weight | 2.27 grams | 2.50 grams |
| Edge Color | Copper/Red Stripe | Solid Silver/White |
The Importance of Proof Grading (PR69 vs. PR70)
When dealing with modern proof coins like the 2018-S Roosevelt Dime, the grade is everything. The Sheldon Grading Scale goes up to 70. A PR69 coin is nearly perfect but might have a tiny, microscopic flaw visible only under magnification. A PR70 is a “perfect” coin.
The price difference between these two grades can be substantial. While a PR69 2018-S Silver Dime might sell for $12, a PR70 Deep Cameo (DCAM) version could fetch three to four times that amount. The “Deep Cameo” designation refers to the sharp contrast between the frosted design and the mirror-like background.

Are There Any Rare 2018-S Dime Errors?
While the San Francisco Mint has extremely high quality control standards for proof coins, errors can occasionally slip through. However, modern errors are quite rare. Most “irregularities” found by casual collectors are actually environmental damage or “post-mint damage” (PMD) rather than true mint errors.
Some collectors look for “Struck Through” errors, where a piece of debris gets caught between the die and the planchet. Others might look for die cracks or double dies, though no major doubled die varieties have been officially recognized for the 2018-S dime yet.
If you suspect you have found an error, CoinKnow is a great resource for comparing your coin with known error databases. It helps avoid the common mistake of thinking a scratched coin is a rare mint error.
| Potential Error Type | Rarity | Estimated Value |
|---|---|---|
| Off-Center Strike | Extremely Rare | $50 – $100+ |
| Struck Through | Very Rare | $20 – $50 |
| Proof Double Die | None Confirmed | N/A |
How to Store and Protect Your 2018-S Dime
Since the 2018-S Roosevelt Dime is a proof coin, its value is tied directly to its surface quality. Even the slightest fingerprint can cause permanent damage over time due to the oils in human skin. If you have a proof dime that is currently in a plastic holder or a mint set, it is best to leave it there.
If your coin is loose, you should handle it only by the edges and store it in a PVC-free coin flip or a hard plastic capsule. Silver coins, in particular, are prone to toning (color changes) when exposed to air and humidity. While some collectors love “rainbow toning,” others prefer the original white luster.
Keeping your coins protected ensures that if you decide to sell them in the future, they will still command the top-tier prices seen in recent auctions.
Summary of the 2018-S Roosevelt Dime Worth
In conclusion, while the 2018-S Roosevelt Dime won’t make you a millionaire, it is a beautiful piece of modern minting history. The clad versions are affordable entries for new collectors, while the silver proof versions offer intrinsic metal value alongside their numismatic appeal.
Always remember to check for that “S” mint mark and verify the edge of the coin to determine if you have the silver variety. With a little bit of research and the right tools, you can accurately value your pocket finds or inherited collections.
FAQ
Q: Why does my 2018-S dime look extra shiny?
A: Your dime is likely a “Proof” coin. These are made with specially polished dies and blanks to create a mirror-like finish for collectors. They are not released into general circulation by the Mint.
Q: Is a 2018-S dime worth silver?
A: Only if it is the “Silver Proof” version. These are 90% silver. If the edge of the coin shows a copper stripe, it is the clad version and contains no silver.
Q: How many 2018-S Roosevelt Dimes were made?
A: The U.S. Mint produced approximately 511,000 Silver Proof sets and about 700,000 standard Clad Proof sets in 2018. Compared to the hundreds of millions of regular dimes, these are quite limited.
Q: Can I find a 2018-S dime in my change?
A: It is very rare but possible. This usually happens when someone accidentally spends a collector’s set or when a collection is stolen and “dumped” into circulation. If you find one, it is likely “impaired” and worth $1-$2 due to wear.
