2018-S Silver Roosevelt Dime Value: Is Your Coin Rare?
The 2018-S Silver Roosevelt Dime is worth anywhere from $8 in Proof-65 condition to over $50 for high-grade specimens. While it may look like the change in your pocket, this specific version was minted for collectors and contains 90% silver, making it a prized find for everyday Americans.
| Grade / Condition | Estimated Market Value |
|---|---|
| PR-65 (Deep Cameo) | $8.00 – $12.00 |
| PR-69 (Deep Cameo) | $15.00 – $18.00 |
| PR-70 (Perfect Condition) | $35.00 – $55.00 |
Identifying Your 2018-S Silver Roosevelt Dime
If you have stumbled upon a gleaming dime dated 2018 with an “S” mint mark, you aren’t looking at a standard circulation coin. To accurately identify your find, you can use a free coin identifier app to verify its specific features. The standard dimes you get as change at the grocery store are made of a copper-nickel alloy. However, the 2018-S Silver Roosevelt Dime was produced specifically by the San Francisco Mint in 90% silver as part of the annual Silver Proof Set.
Because these coins were never intended for general circulation, finding one in your pocket change is rare. It usually means someone accidentally spent a coin from a collector’s set. These coins are known for their “Proof” finish, which features mirror-like backgrounds and frosted details on the portrait of Franklin D. Roosevelt.
When you use an app like CoinKnow, you can quickly determine if your coin is the silver version or the standard clad version. The weight is the biggest giveaway. A standard dime weighs 2.27 grams, while the silver version weighs 2.50 grams. This slight difference in weight translates to a significant difference in value due to the precious metal content.
The Silver Content and Melt Value Factor
One of the reasons the 2018-S Silver Roosevelt Dime holds a higher value than its face value is its 90% silver composition. In 2018, the United States Mint was still using the traditional alloy for silver proof sets (they switched to .999 fine silver in 2019). This means your coin is literally worth its weight in silver, even if it is scratched or damaged.
| Component | Measurement |
|---|---|
| Silver Purity | 90% Silver, 10% Copper |
| Silver Weight | 0.0723 troy oz |
| Overall Weight | 2.50 Grams |
Check the latest spot price of silver to determine the “melt value.” However, collectors will almost always pay more than the melt price for a clean, undamaged coin. If you are curious about how this compares to non-silver versions, you can view the 2018 dime pricing for regular strikes to see the contrast between business strikes and these silver proofs.
Why the ‘S’ Mint Mark Matters
The mint mark on a Roosevelt dime is located on the obverse (front) of the coin, just above the year. If you see a small “S,” it indicates the coin was minted in San Francisco. While the Philadelphia (P) and Denver (D) mints produced hundreds of millions of dimes for everyday use, the San Francisco Mint focused on limited editions for collectors.
The 2018-S Silver Roosevelt Dime was produced in much lower quantities than its copper-nickel counterparts. Because it wasn’t made to be spent, most of these coins have been kept in protective plastic cases. If you find one that is “raw” (loose), it may have lost some value due to handling, but it still remains a collectible piece.
Tools like CoinKnow are excellent for hobbyists who want to keep track of their collection’s scarcity. Knowing exactly how many silver proofs were produced in 2018 allows you to understand why sellers might ask for $10 or more for a coin that says “10 cents” on the back.
Understanding the Proof-70 Grade
In the world of coin collecting, the condition is everything. Coins are graded on a scale from 1 to 70. A “Proof-70” coin is considered perfect, with no visible flaws even under 5x magnification. For the 2018-S Silver Roosevelt Dime, hitting this perfect grade significantly bumps up the price.
Most 2018-S silver dimes will be “Deep Cameo” (DCAM). This means there is a heavy contrast between the shiny, mirror-like fields and the duller, frosted image of Roosevelt. If your coin looks “flat” or doesn’t have that mirror shine, it might be a standard clad proof or simply very worn.
For a deeper dive into the specific market trends, you can check this detailed guide on 2018 dime values to see how condition impacts the final sale price at auctions. Collectors are often willing to pay a premium for “First Strike” or “Early Release” labels provided by professional grading services like PCGS or NGC.
Rare Errors to Look For
While proof coins are struck under high pressure and inspected closely, errors can still occur. For the 2018-S Silver Roosevelt Dime, errors are exceptionally rare, which makes them highly valuable. Keep an eye out for “doubled dies,” where the lettering or the date appears to have a secondary ghost image.
Another potential error is a “clipped planchet,” where the coin looks like a bite was taken out of the edge. Because these coins are part of a prestige set, the quality control at the San Francisco Mint is much higher than in Philadelphia or Denver. Finding an error on a 2018-S silver coin is like winning the lottery for a coin hunter.
Using CoinKnow to scan your coin can help you zoom in on these tiny details. If you suspect an error, it is often worth the investment to have it professionally authenticated, as a confirmed error coin can sell for hundreds of dollars depending on the severity of the mistake.
Collecting the 2018 Roosevelt Dime Series
For many Americans, the 2018 series is an accessible way to start a coin collection. Instead of just focusing on the 2018-S Silver Roosevelt Dime, many people try to find all four versions from that year: the P, D, S-Clad, and S-Silver.
| Mint Mark | Composition | Rarity Level |
|---|---|---|
| P (Philadelphia) | Copper-Nickel | Common |
| D (Denver) | Copper-Nickel | Common |
| S (San Francisco) | Copper-Nickel Proof | Uncommon |
| S (San Francisco) | 90% Silver Proof | Scarce |
Building a complete set for a specific year is a fun and educational hobby. It teaches you how to distinguish between different manufacturing processes and materials. Always handle your silver dimes by the edges to avoid leaving fingerprints, as the oils from your skin can damage the delicate proof finish over time.
FAQ
Q: How can I tell if my 2018-S dime is silver without a scale?
A: Look at the edge of the coin. A standard clad dime will have a visible copper stripe around the side. A silver dime will have a solid, bright silver edge with no copper showing. Additionally, silver dimes have a higher-pitched “ring” when gently tapped.
Q: Is a 2018-S silver dime more valuable than an older silver dime?
A: Generally, no. Silver dimes from 1964 and earlier are very common and their value is mostly tied to the silver price. However, since the 2018-S is a Proof coin with a much lower mintage than “junk silver” dimes, it often carries a higher collector premium.
Q: Where can I sell my 2018-S Silver Roosevelt Dime?
A: You can sell it to local coin shops, through online marketplaces like eBay, or at coin shows. For a quick estimate of what dealers might offer, check your CoinKnow app for recent “sold” listings to see what buyers are actually paying.
Q: Does the 2018-S dime contain pure silver?
A: No, it is 90% silver and 10% copper. This was the standard for US Mint silver proof sets in 2018. The Mint didn’t switch to .999 (99.9%) fine silver for these sets until the following year, 2019.
