Most dimes in circulation are only worth ten cents, but a few seemingly ordinary ones have shocked collectors by selling for thousands—or even hundreds of thousands—of dollars. Whether due to minting errors, low mintage, or historical significance, these dimes have become some of the most sought-after coins in numismatic history. If you’ve got an old dime lying around, it might be worth far more than you think! Here are three ordinary dimes that turned into a collector’s dream.
1. 1965 Silver Roosevelt Dime – A Rare Minting Error
In 1965, the U.S. Mint switched from silver coins to a copper-nickel composition. However, a small number of 1965 Roosevelt dimes were mistakenly struck on leftover 90% silver planchets from 1964. These silver dimes look identical to regular ones, but they weigh 2.5 grams instead of 2.27 grams. If you find one, you’re looking at a coin that could sell for $5,000 to $10,000 at auction!
2. 1982 No Mint Mark Roosevelt Dime – A Printing Mishap
Most U.S. dimes have a small letter (P, D, or S) indicating where they were minted. However, in 1982, a batch of dimes struck at the Philadelphia Mint accidentally left off the “P” mint mark. These error dimes made their way into circulation, and because they were unintentional, they became highly collectible. A 1982 No Mint Mark dime in top condition can fetch $500 to $1,500 depending on its grade.
3. 1970-S Proof Roosevelt Dime (No “S” Mint Mark)
Proof coins are specially minted for collectors, and they always include a mint mark. But in 1970, a small number of proof dimes were mistakenly struck without the “S” mint mark from the San Francisco Mint. These rare dimes are highly sought after because proof coins with missing mint marks are incredibly rare. A 1970 No-S Proof Dime can easily sell for $2,500 to $10,000, making it one of the most valuable dimes of the modern era.
These three ordinary dimes became legendary in the coin-collecting world due to unexpected minting mistakes and rare occurrences. Whether it’s a 1965 silver error, a 1982 no-mint-mark dime, or a 1970 No-S proof, these coins have transformed from pocket change into collector’s treasures. If you have old dimes, it’s worth checking them closely—you never know if you might be holding a small fortune!
FAQ’s:
1. How can I check if my 1965 dime is silver?
Weigh the coin! A silver 1965 dime should weigh 2.5 grams, while a regular copper-nickel version weighs 2.27 grams.
2. Where can I sell a rare dime?
You can sell valuable dimes at coin shops, online auctions (eBay, Heritage Auctions), or through professional numismatic dealers.
3. Why do missing mint marks make a coin valuable?
Missing mint marks are rare minting errors, making them highly desirable among collectors who seek unique coins.
4. How do I know if my 1970 dime is a rare proof version?
