Roosevelt dimes are among the most familiar U.S. coins — yet hidden within everyday change are a handful of scarce dates, mint errors, and desirable varieties that can be worth far more than their face value. In 2026, demand for rare Roosevelt dimes remains strong among collectors and investors, with certain issues commanding five-figure prices at auction.
Whether you’re a seasoned numismatist or just beginning to explore coin collecting, this guide highlights the top 5 rare Roosevelt dimes to watch in 2026, what makes each one valuable, and tips for spotting them.
Why Some Roosevelt Dimes Are Valuable
Before we dive in, it’s helpful to understand why certain Roosevelt dimes are worth significantly more than others:
Rarity: Some coins exist in very low numbers or unexpected varieties.
Condition: Coins graded MS65 or higher by PCGS, NGC, or ANACS can see major price increases.
Mint Errors & Oddities: Missing or misplaced mintmarks, doubled dies, and other striking errors are collectible.
Silver Composition: Dimes from 1946–1964 are 90% silver, adding both intrinsic and collectible value.
1. 1975 No-S Proof Roosevelt Dime — The King of Rarities
Why It’s Rare:
The 1975 No-S Proof Roosevelt dime is by far the most coveted in the series. Proof coins from the San Francisco Mint should carry an “S” mintmark — but this variety was struck without it, creating a coin that “shouldn’t exist.” Only two certified examples are currently known.
Estimated 2026 Value:
$350,000–$500,000+ — auctions have reached well into six figures due to intense collector demand.
Identification Tips:
- Mirror-like proof surface with frosted design details
- No “S” mintmark on a coin that is otherwise unmistakably a 1975 proof
- Professional grading is essential for authentication
Because of its rarity and dramatic history, this dime is typically the centerpiece of any serious Roosevelt collection.
2. 1968 No-S Proof Roosevelt Dime — A Scarce Modern Error
Why It’s Rare:
Much like the 1975 example, the 1968 No-S Proof dime resulted from a mintmark omission on coins intended for San Francisco proof sets. These errors are much rarer than standard proof issues and highly prized when found in pristine condition.
Estimated 2026 Value:
$40,000–$60,000+ in high certified grades.
Why Collectors Love It:
This dime combines the appeal of a modern production error with strong proof quality and limited known survivors.
3. 1950-S Roosevelt Dime — Silver Era Classic
Why It’s Rare:
The 1950-S Roosevelt dime was minted in San Francisco with a relatively modest mintage, and most examples seen today are worn from circulation. Well-preserved high-grade coins — especially Mint State (MS65+) with original luster — are relatively scarce and highly sought after.
Estimated 2026 Value:
$10,000–$30,000+ for top MS examples.
Collector Notes:
- Silver composition (90%) attracts both bullion and numismatic interest
- Sharply struck surfaces with minimal wear are especially desirable
4. 1949-S Roosevelt Dime — A High-Grade Silver Treasure
Why It’s Rare:
One of the earlier San Francisco silver Roosevelt dimes, the 1949-S is common in circulated grades but unusual in high mint state condition. Deep luster and clear strike details dramatically affect value.
Estimated 2026 Value:
$8,000–$25,000+ for top certified Mint State examples.
Identification Tips:
- Strong, sharp details on Roosevelt’s profile
- Bright, untarnished silver surfaces
- Clear “S” mintmark on the reverse
Silver era dimes are perennially popular because they combine precious metal content with historical significance.
5. 1968-D Doubled Die Roosevelt Dime — A Premium Error Variety
Why It’s Rare:
The 1968-D doubled die Roosevelt dime features noticeable doubling on the date or lettering, a striking anomaly created during die preparation that wasn’t corrected. This kind of error variety commands attention among numismatists.
Estimated 2026 Value:
$5,000–$15,000+ depending on the severity of the doubling and the coin’s condition.
Collector Appeal:
- Globe-wide interest from error coin collectors
- Grading and certification increase auction visibility
- Not silver, but rarity drives value
Value Comparison: Top 5 Rare Roosevelt Dimes (2026)
| Roosevelt Dime | Notable Feature | Estimated Value (2026) |
|---|---|---|
| 1975 No-S Proof | Proof missing mintmark; only 2 known | $350,000+ |
| 1968 No-S Proof | Proof error, no “S” | $40,000–$60,000 |
| 1950-S Silver | San Francisco high-grade rarity | $10,000–$30,000 |
| 1949-S Silver | Early silver Mint State rarity | $8,000–$25,000 |
| 1968-D Doubled Die | Error doubling increases value | $5,000–$15,000 |
How to Spot Valuable Roosevelt Dimes
1. Check the Mintmark (or Its Absence)
Mintmarks like “S” (San Francisco), “D” (Denver), and “P” (Philadelphia) help identify rare issues — and the absence of one where it should appear can signal an error.
2. Look for Silver Content (1946–1964)
Roosevelt dimes minted before mid-1965 are 90% silver. While not all silver dimes are scarce, many valuable ones come from this era in high grade.
3. Examine Strike Quality and Doubling
Strong strikes with full details and unusual die doubling often indicate premium varieties that may be undervalued in casual circulation.
4. Professional Grading Is Key
Certification by PCGS, NGC, or similar services adds confidence and often boosts market value.
Tips for Collectors in 2026
- Use a magnifying glass or loupe to inspect subtle details like doubled dies or mintmark errors.
- Always compare with reference photos from reputable coin guides.
- Don’t assume every off-mintmark dime is rare — many date ranges (e.g., 1965–1967) had no mintmarks as standard.
- Condition and grading matter far more than age alone — the same date can vary greatly by grade.
