Rare error dimes have recently become a major focus among coin collectors, especially after two such coins were sold for an astounding $850,000 combined. These seemingly ordinary coins have extraordinary value due to unique minting errors, making them highly coveted in the numismatic world. For both collectors and hobbyists, these error coins offer a fascinating glimpse into the potential hidden value of everyday change.
In this article, we’ll delve into the two remarkable dimes that sold for such eye-popping prices: the 1968-S No-S Proof Roosevelt Dime and the 1975 No-S Proof Roosevelt Dime. Additionally, we’ll explore how to identify rare error coins and why these unique coins are so highly sought after.
What Makes Rare Error Dimes So Valuable?
Coin | Details | Recent Sale Price | Why It’s Rare |
---|---|---|---|
1968-S No-S Proof Dime | Proof coin with a missing “S” mintmark | Over $400,000 | Few exist; a significant minting mistake |
1975 No-S Proof Dime | Proof coin missing the “S” mintmark; only two known | $450,000 | Among the rarest proof dimes in history |
Why Do Rare Error Dimes Fetch Such High Prices?
Unintended Rarity
Minting errors occur when coins are struck incorrectly, leading to rare pieces that can be worth far more than their face value. Unlike coins that are mass-produced, error coins have unique characteristics that make them stand out. For example, the 1968-S No-S Proof Dime and the 1975 No-S Proof Dime both lack the “S” mintmark, which identifies proof coins minted in San Francisco. These minting oversights have made these error coins exceptionally valuable.
Historical and Numismatic Appeal
Error coins carry a unique historical story about the minting process, which gives them an added layer of significance. Their imperfections are not seen as flaws but rather rare anomalies that make them desirable to collectors.
Collector Demand
For many coin enthusiasts, error coins represent the ultimate find, especially those that are extremely rare like the 1975 No-S Proof Dime, with only two known examples in existence. This intense demand among collectors increases their market value.
The 1968-S No-S Proof Dime: A Minting Mistake That Became a Treasure
The 1968-S No-S Proof Dime perfectly illustrates how a minor minting mistake can result in a coin worth hundreds of thousands of dollars. Proof coins are specially made for collectors, featuring sharp details and polished finishes. They are typically subjected to rigorous quality control, making errors like the missing “S” mintmark extremely rare. These dimes, which should have featured the “S” mintmark under the date, were mistakenly struck without it. One such coin recently sold for over $400,000, underlining its incredible value.
The 1975 No-S Proof Dime: The Rarest of Them All
The 1975 No-S Proof Dime is even rarer. With only two known examples, this coin is one of the most valuable in U.S. numismatics. Like the 1968 version, it was struck without the “S” mintmark, but its rarity is unmatched. Collectors prize this coin not only for its scarcity but also for its historical significance. At auction, one of these coins was sold for $450,000, cementing its place as one of the highest-valued dimes in the world.
How to Identify Rare Error Dimes
1. Check for Missing Mintmarks
Proof coins from the San Francisco Mint should bear an “S” mintmark below the year. A missing mintmark is a key indicator that you may have a rare error coin.
2. Inspect the Condition
The value of error coins is significantly higher if they are in near-perfect condition. Look for coins with minimal wear and a sharp, mirror-like finish, which is typical for proof coins.
3. Look for Other Unique Features
Additional minting errors, such as overdates or doubled dies, can also make a coin more valuable. A magnifying glass or coin loupe can help identify these subtle details.
4. Seek Professional Grading
If you think you have a rare error coin, it’s wise to have it authenticated and graded by professionals like the Professional Coin Grading Service (PCGS) or the Numismatic Guaranty Corporation (NGC). Their certification not only verifies authenticity but can also increase the resale value of the coin.

While rare error dimes are fascinating, they are not the only valuable error coins. Here are a few others that have captured the attention of collectors:
