1. The Legendary 1894-S Barber Dime
With only 24 ever minted and fewer than 10 known to still exist, the 1894-S Barber Dime is considered a unicorn in the coin world. In excellent condition, this coin has sold at auction for nearly $2 million.
What to Look For:
- “S” mint mark below the wreath
- Crisp detailing on Liberty’s head
- Proof-like finish
2. 1916-D Mercury Dime
This was the first year the Mercury Dime was issued, and the Denver Mint only produced 264,000 of them. That number makes it one of the lowest minted dimes of the 20th century.
Watch for:
- “D” mint mark on the reverse
- Sharp details, especially in mint state
3. 1942/1 Mercury Dime Overdate Error
Due to a minting mistake, some 1942 dimes show a visible “1” beneath the “2” in the date. These “overdate” errors are rare and in high demand.
Worth:
- Up to $75,000, depending on condition
4. 1975 No S Roosevelt Dime (Proof Only)
This is one of the rarest modern coins, as only two are known to exist. These proof coins were struck without the “S” mint mark in San Francisco.
Current Estimated Value:
- Around $500,000
5. 1968 No S Roosevelt Dime (Proof)
Similar to the 1975 version, these proof dimes accidentally left the San Francisco Mint without the “S” mark.
Value:
- Around $20,000 – $30,000
6. 1873-CC No Arrows Seated Liberty Dime
The only known example of this coin exists, making it a true one-of-a-kind gem. It was minted in Carson City with no arrows next to the date.
Sold for:
- Over $1 million
7. High-Grade 1916-D Mercury Dime
While we’ve listed the 1916-D already, it’s worth emphasizing that mint-state versions (uncirculated and professionally graded) can push values over $200,000.
8. The 1976 Bicentennial Quarter
This quarter was minted to commemorate America’s 200th birthday. Most are common, but silver-clad collector’s versions and those with minting errors can be worth a small fortune.
Rare Varieties Include:
- 40% silver-clad proofs
- Double die errors
- Off-center strikes
Value:
- Up to $25,000+ for rare versions
Who knew spare change could be worth more than a luxury car—or even a house? These dimes and quarters aren’t just currency; they’re historical artifacts and potential windfalls.
So next time you’re handed change, take a closer look—you might be holding a piece of the $357 million coin club.
