Roosevelt dimes have been circulating since 1946, but only a handful contain the rare errors, mint varieties, or silver compositions that make them worth hundreds, thousands, or even tens of thousands of dollars today. While most are worth face value, the rare ones can turn an ordinary pocket find into a life-changing collectible.
Here is your 2026 collector’s guide to the top 5 most valuable Roosevelt dimes and exactly how to identify them.
1. 1968 No-S Proof Roosevelt Dime – One of the Rarest Modern Coins
The 1968 No-S proof dime is one of the most valuable modern U.S. coins because it was accidentally struck without the “S” mintmark at the San Francisco Mint.
Why it’s valuable:
• Very limited mintage due to minting error
• Only a handful are confirmed to exist
• Highly demanded by proof coin collectors
Estimated value: $10,000 to over $40,000 in top condition.
2. 1975 No-S Proof Roosevelt Dime – Virtually Unknown and Extremely Rare
Another mintmark error, the 1975 No-S proof dime is even rarer than the 1968 version. Only two confirmed examples are known to exist.
Key features:
• No “S” mintmark on a proof-only issue
• Strong mirrorlike surfaces
• Considered one of the rarest modern dimes ever made
Estimated value: Up to $500,000 or more depending on grade.
3. 1982 No-P Roosevelt Dime – First Circulation Strike Missing a Mintmark
In 1982, the Philadelphia Mint mistakenly released dimes lacking the “P” mintmark, making it the first circulation dime with this error.
| Feature | Normal 1982 Dime | Rare 1982 No-P Dime |
|---|---|---|
| Mintmark | “P” on obverse | No mintmark at all |
| Strike type | Business strike | Error circulation strike |
| Value | Face value | $150 to $1,000+ |
These coins commonly show strong details and appear similar to normal dimes, so careful inspection is needed.
4. 1949-S Roosevelt Dime – A Rare Early-Mint Silver Issue
Before 1965, all Roosevelt dimes were .900 fine silver. The 1949-S stands out among early issues due to its low mintage and scarcity in high grades.
Why collectors want it:
• One of the lowest early Roosevelt dime mintages
• Often weakly struck, high-grade examples extremely rare
• Silver composition adds extra appeal
Estimated value: $50 to $5,000+ depending on grade.
5. 1964-D Doubled Die Reverse Dime – Rare and Highly Misidentified
The 1964-D doubled die reverse is one of the most prized silver Roosevelt dime varieties, but it is often overlooked because the doubling is subtle.
What to look for:
• Strong doubling on the torch and olive branches
• Thickened letters on “UNITED STATES OF AMERICA”
• Only confirmed on Denver-minted 1964 versions
Estimated value: $300 to over $7,000 in higher grades.
How to Identify Rare Roosevelt Dimes at Home
• Check for missing mintmarks (“P,” “S,” or “D”)
• Use a magnifier to spot doubling on letters or the torch
• Compare weight and sound for silver content
• Look for unusually sharp or unusually weak strikes
• Inspect rims for misalignment, broad strikes, or off-center errors
A simple magnifying glass or your phone’s zoom function can reveal most valuable details.
Conclusion:
Roosevelt dimes may seem ordinary, but several rare dates and error varieties can be worth thousands of dollars in today’s collectible market. The 1968 No-S, 1975 No-S, 1982 No-P, 1949-S silver issue, and 1964-D doubled die are among the most sought-after pieces heading into 2026. By learning their key identifiers, collectors and everyday coin hunters can potentially uncover hidden treasures in pocket change or old coin jars.
