Roosevelt Dimes: Rare Roosevelt dimes have surprised collectors for decades. While most dimes are worth only face value, a few special issues and mint errors have sold for thousands of dollars at auction. These coins often hide in old proof sets, collections, or even everyday change.
From the famous 1975 No-S proof dime to high-grade silver issues, certain varieties stand out. Understanding mint marks, proof finishes, and grading can help identify valuable pieces. With careful inspection and proper authentication, an ordinary ten-cent coin could turn into a remarkable treasure.
Why Rare Roosevelt Dimes Are Highly Valuable
Some Roosevelt dimes are valuable because of minting mistakes or extremely low survival numbers. Coins like the 1975 No-S proof dime are rare due to production errors, making them highly desirable among collectors. Rarity combined with demand drives prices into the thousands.
Condition also plays a major role. High-grade coins certified by professional grading services often sell for far more than average circulated examples. A common silver dime in poor condition may be worth melt value, while a superb specimen can bring impressive auction results.
The Famous 1975 No-S Proof Roosevelt Dime
The 1975 No-S proof Roosevelt dime is one of the rarest modern U.S. coins. Only two confirmed examples are known. One example sold for $506,250 at auction, making it one of the most valuable dimes ever recorded.
This coin was struck at the San Francisco Mint but lacks the expected “S” mint mark. It features mirror-like proof surfaces and sharp details. Because of its rarity and documented sales history, it remains a headline coin in numismatic circles.

Silver Roosevelt Dimes From 1946 to 1964
Roosevelt dimes minted between 1946 and 1964 contain 90 percent silver. Even common examples are worth more than face value due to their silver content. Their intrinsic metal value provides a base price floor.
However, coins in exceptional condition can be worth much more. High-grade examples with full details and strong strike quality have sold for thousands at auction. Certified pieces from certain mint locations are especially sought after.
High-Grade 1947-D Roosevelt Dime Auction Results
The 1947-D Roosevelt dime is a notable example of how condition affects value. In average condition, it may only be worth modestly above melt value. Yet in top certified grades, it has achieved auction prices around $7,700.
Collectors look for sharp details and strong strike characteristics. Coins graded at the highest levels by professional services often attract competitive bidding. This demonstrates how a common date can become valuable in extraordinary condition.
Doubled Die Roosevelt Dimes Worth Thousands
Doubled die errors occur when the coin design is impressed more than once in slightly different positions. This creates visible doubling on letters, numbers, or design elements. Strong doubling can significantly increase value.
Collectors carefully examine areas like the date, LIBERTY, and IN GOD WE TRUST. Prominent doubled die examples in high grades can command strong premiums. The clearer and more dramatic the doubling, the greater the collector interest.
Repunched Mint Mark Varieties and Their Value
Repunched mint marks appear when the mint mark is struck more than once in slightly different positions. This creates a noticeable overlapping effect. These varieties are popular among specialists who collect error coins.
Although not all RPM varieties are worth thousands, rare or high-grade examples can carry strong premiums. Careful inspection with magnification is essential. Coins authenticated and certified often achieve higher prices in the market.
Other Missing Mint Mark Proof Dimes
In addition to the 1975 No-S rarity, other proof dimes from the late 1960s and 1970s have been reported with missing mint marks. These coins were intended to display a mint mark, typically “S” for San Francisco.
Such errors are uncommon and attract serious attention from collectors. Value depends on verification, condition, and rarity. Authentication by professional grading services is essential before assigning significant market value.
How To Identify A Valuable Roosevelt Dime
Start by checking the year and mint mark. Dimes from 1946 to 1964 are silver, while later issues are copper-nickel clad. Look closely for missing mint marks, unusual doubling, or striking errors.
Next, examine the coin’s surface. Proof coins have mirror-like backgrounds and sharp details. Avoid cleaning the coin, as this reduces value. If the coin appears unusual, consider professional evaluation and grading.
What To Do If You Find A Rare Dime
If you suspect your dime is valuable, handle it carefully by the edges. Place it in a protective holder to prevent scratches or damage. Proper storage preserves its condition and potential value.
Seek professional authentication from a trusted grading service. Certified coins often sell for higher prices due to buyer confidence. With patience and proper verification, a small coin can become a significant financial discovery.
