Could one of the smallest coins in your pocket really be worth $9.8 million? According to coin collectors and treasure hunters, a rare Roosevelt dime might just be hiding in plain sight — if it’s the right kind of rare. While most Roosevelt dimes are worth face value or slightly more for their silver content, a few unique varieties are extraordinarily rare and highly sought after.
Here’s everything you need to know about this legendary coin, what makes it so valuable, and how to check if you’re holding one of these numismatic unicorns.
The Roosevelt Dime: A Quick Overview
- Introduced: 1946 (replacing the Mercury dime)
- Designed by: John R. Sinnock
- Honors: President Franklin D. Roosevelt
- Composition (1946–1964): 90% silver, 10% copper
- Post-1965 Composition: Clad (copper-nickel)
Millions were made, but not all are created equal.
Why Would a Roosevelt Dime Be Worth $9.8 Million?
Most Roosevelt dimes are worth just 10 cents, or slightly more for silver ones. But under specific and extremely rare conditions, a single error or prototype dime could potentially be worth millions. Here’s why:
Possible Candidates for the $9.8 Million Dime
1. 1964-D Roosevelt Dime Struck on a 90% Silver Planchet
- In 1965, the U.S. Mint transitioned from silver to clad coinage.
- Some transitional errors occurred — dimes minted in 1965 using 1964 silver blanks.
- These transitional errors are rare and have sold for thousands to tens of thousands.
2. 1982 No Mint Mark Dime
- In 1982, some dimes from the Philadelphia Mint were struck without a mint mark, which was unusual.
- These “No P” coins are rare and can be worth hundreds to thousands depending on condition.
3. Proof or Experimental Strikes
- Occasionally, experimental or prototype coins (not meant for public release) are struck.
- If one were made from the wrong metal, had a unique die pairing, or came from a never-released mint process, it could reach astronomical value — especially if it’s the only known example.
4. Off-Metal or Wrong Planchet Errors
- If a Roosevelt dime was accidentally struck on a foreign coin planchet, it could be unique.
- Similar rare off-metal errors have fetched five- to six-figure prices at auctions.
🟢 If a one-of-a-kind Roosevelt dime were discovered — such as a prototype or an undisclosed Mint test strike — the coin could theoretically sell for millions in a private or public auction.
How to Check If You Have a Valuable Roosevelt Dime
Key Things to Look For:
- Mint Year:
- 1964 or earlier = 90% silver
- 1965 transitional errors are highly valuable
- 1982 “No P” error dimes
- Mint Mark Location:
- Found on the obverse (front), near Roosevelt’s neck.
- Weight Check:
- Silver dimes weigh 2.5 grams
- Modern clad dimes weigh 2.27 grams
- Error Indicators:
- No mint mark when one should be present
- Double die or off-center strike
- Unusual metal color or luster
- Weak or missing details
- Proof Quality:
- Mirror-like finish, sharp details, deep cameo contrast
What to Do If You Think You Have the $9.8 Million Dime
- Handle Carefully – Use gloves and hold the coin by its edge.
- Do NOT Clean It – Cleaning decreases value dramatically.
- Weigh and Photograph – Use a digital scale and take clear images.
- Get It Graded – Submit it to a professional grading service like PCGS or NGC.
- Consult a Reputable Coin Dealer – They can help authenticate and appraise it.
