Sometimes the tiniest missing detail can make a massive difference—especially when it comes to coins. The 1968 No S Proof Roosevelt Dime is one such example, where the absence of a small mint mark has transformed an otherwise ordinary coin into one of the most valuable dimes ever known. This rare error, produced in extremely limited numbers, has captured the attention of collectors and investors alike. Recently, one such dime was valued at over $9 million, making it one of the highest-priced U.S. coins of its kind.
1968 No S Proof Roosevelt Dime – A Minting Mishap
The 1968 Roosevelt Dime was intended to carry the “S” mint mark, signifying it was struck at the San Francisco Mint. However, in a rare oversight, a small number of proof dimes were produced without the mint mark, resulting in what is now known as the “No S” Proof error. Since these proof coins were only meant for collectors and not for general circulation, the error went unnoticed—until a few sharp-eyed numismatists discovered the anomaly.
Only a handful of these 1968 No S dimes are known to exist. Their proof finish (mirror-like background and frosted details) combined with the missing mint mark makes them extremely rare. The absence of the “S” on the obverse is what sets this coin apart and drives its multimillion-dollar value.
Why It’s Worth Over $9 Million
So why would a dime missing a single letter be worth a fortune? It all comes down to rarity, condition, and historical significance. First, only a very limited number of 1968 No S Proof Roosevelt Dimes were ever minted—likely by accident. Most were caught and corrected, but a few escaped into collectors’ hands.
Second, the coin’s proof status means it was struck with special care for collectors, using polished dies that create a sharp and reflective finish. When a proof coin is discovered with such a significant error, its rarity increases exponentially. A flaw on a collector’s item designed for perfection makes it an irresistible target for high-end buyers. In one recent private sale, a pristine example of the 1968 No S Proof Roosevelt Dime sold for more than $9 million, astonishing even seasoned coin experts.
In the world of rare coins, even a dime can change your life. The 1968 No S Proof Roosevelt Dime is a shining example of how a small minting error, preserved in perfect condition, can become one of the most desirable coins in American history. It reminds us to look closely at our collections—or even our pocket change—because you never know when a forgotten detail could be worth millions.
FAQ’s:
1. How can I tell if I have a 1968 No S Proof Dime?
Check the obverse (front) of the coin just above the year. If there is no “S” mint mark and the coin has a mirror-like proof finish, it may be the rare version.
2. Were any 1968 No S Dimes released into circulation?
No, these were proof coins meant for collectors. If you find one, it likely came from a broken-up proof set.
3. Why is the missing “S” mint mark important?
The “S” indicates the San Francisco Mint. Its absence on a proof coin meant to include it is a major minting error, increasing the coin’s rarity and value.
4. How many of these coins exist?
Experts estimate that less than a dozen 1968 No S Proof Dimes are known, making it one of the rarest modern coins.
5. What should I do if I think I found one?
Immediately consult a reputable coin grading service like PCGS or NGC for authentication. If genuine, your coin could be worth a fortune.
