Let’s break down the particular coins collectors are searching for.
Rare Dimes That Could Be Worth a Fortune

1975 No-S Roosevelt Dime
This extremely rare coin was accidentally minted at the San Francisco Mint without the “S” mint mark. Only two are known to exist. One was sold at auction for $456,000, and another sold for more than $500,000 in 2024.
1894-S Barber Dime
Just 24 of these dimes were produced, and fewer than 10 are known to exist today. One is sometimes called the “King of Dimes,” and one sold for more than $1.3 million at auction recently.
1916-D Mercury Dime
This dime was struck for only 264,000 pieces and is particularly valuable in the uncirculated state. The prices can range from several thousand dollars to well over $200,000.
The 1976 Bicentennial Quarter: A Collector’s Favorite
To commemorate the United States Bicentennial, the United States Mint minted special quarters with a design of a drummer. Although most of these are common and are only face value, some of the rare errors and varieties found their way into circulation.
Collectible Bicentennial Quarter Varieties
- No-S Proof Quarter – Mint mark missing errors can sell from $7,000 to $20,000.
- Double Die Obverse – Doubling on text or image can significantly hike the price.
- Silver Clad Proofs – A few Bicentennial quarters were struck in 40% silver, initially sold in collector sets. These are worth more than regular clad versions.
