What Makes the 1975 No-S Dime So Valuable?
Understanding Mint Marks
Most U.S. proof coins are struck at the San Francisco Mint, which uses an “S” mint mark. These coins are collector’s items, made with extra care for clarity, shine, and detail.
But in 1975, a rare mistake occurred.
One of the dies used to strike proof Roosevelt dimes was missing the “S” mint mark. That meant some proof coins appeared to have been made at a mint that doesn’t produce proof coins—a highly unusual occurrence.
Since only two examples of the 1975 No-S Proof Dime are known to exist, this microscopic error created a coin worth more than half a million dollars.
The Coin’s Incredible Journey
The story gets even more interesting after the coin was made:
- In 1978, an Ohio family purchased the dime for $18,200, recognizing its investment potential.
- They stored it safely in a bank vault for over 40 years.
- In 2024, the coin was inherited by three sisters, who consigned it to GreatCollections, a California-based rare coin auction house.
- It sold for $506,250, setting a record for this type of coin.
This story was reported by CBS News, New York Post, and Artnet News.
Why Minting Errors Matter in Coin Collecting
A Lesson in Numismatics
Minting errors—like missing mint marks, double strikes, or off-center coins—make certain coins incredibly desirable in the collecting world. They often fetch significantly higher prices due to their rarity.
A missing mint mark may seem small, but in the case of the 1975 No-S dime, it changes the entire classification of the coin. It becomes:
- An error-proof coin (extremely rare)
- A historical anomaly
- A collector’s dream
These unique errors are certified by organizations like PCGS (Professional Coin Grading Service) and listed in high-authority references like the Red Book—an industry-standard guide for U.S. coin values.
Could There Be More of These Dimes Out There?
That’s the million-dollar question—literally.
According to coin experts and sources like The US Sun, unopened proof sets from 1975 may still contain more of these No-S dimes. That means:
- Collectors and everyday people could unknowingly be sitting on small fortunes.
- You can buy 1975 proof sets on platforms like eBay or check your collection if you have one.
If you suspect you’ve got something special, consult a certified expert or submit your coin to PCGS or NGC (Numismatic Guaranty Company) for authentication.
Step-by-Step Guide: How to Check Your Coins
Step 1: Know What to Look For
Look for proof coins from 1975 that lack the “S” mint mark.
Step 2: Understand What a Proof Coin Looks Like
Proof coins:
- Have a mirror-like finish
- Are struck multiple times for detail
- Come in a protective case (if original)
Step 3: Examine With a Loupe
Use a magnifying glass (10x loupe is ideal) to carefully examine the area below Roosevelt’s neck for a missing mint mark.
Step 4: Get Expert Verification
If you think you’ve found something valuable:
- Contact a local coin shop
- Use PCGS or NGC services to grade and authenticate your coin
Step 5: Consider Selling at Auction
Use platforms like:
- GreatCollections
- Heritage Auctions
- Stack’s Bowers
