It might sound far-fetched, but that ordinary dime rattling around in your piggy bank could be worth a small fortune. For coin collectors and lucky treasure hunters, some coins are more than just currency — they’re valuable artifacts hiding in plain sight. Let’s dive into some of the rarest and most valuable dimes ever minted in the U.S., and why you should take a second look at your spare change.
1894-S Barber Dime
The crown jewel of dimes. Only 24 were minted in San Francisco in 1894, and just nine are known to exist today. Legend has it one was spent on ice cream! If found, even in average shape, this dime can command over $2 million.
1916-D Mercury Dime
With only 264,000 minted in Denver, this is among the rarest Mercury dimes. Even in rough shape, it’s worth thousands. In pristine condition, it could fetch $10,000 to $200,000.
1942/1 Mercury Overdate Dime
This mint error occurred when 1942 dimes were mistakenly struck over 1941 dies, creating a visible overdate. These quirky dimes start around $500, but top examples can exceed $10,000.
1975 No S Proof Roosevelt Dime
Proof coins from San Francisco typically have an ‘S’ mint mark — not these. A handful of 1975 proof dimes were made without it. One of these could be worth $50,000 or more.
1968 No S Proof Roosevelt Dime
A similar mistake happened in 1968, making this proof dime without the ‘S’ incredibly scarce. Depending on condition, it’s valued between $10,000 and $20,000.
1874-CC Liberty Seated Dime
Struck in Carson City during the gold rush, this coin is a piece of Old West history. Only a few are known to survive, and they can be worth as much as $22 million — yes, really.
1798/7 Draped Bust Dime
This dime was made when a 1798 die was struck over a 1797 version, causing a visible date error. It’s a collector’s dream, valued in the millions.
1844 Liberty Seated Dime
Nicknamed “The Little Orphan Annie,” this dime had a very low production run. Though it doesn’t have a dramatic backstory, rarity alone puts its value in the tens of thousands.
