In the vast world of coin collecting, some dimes and Bicentennial coins have risen far beyond their face value. These small pieces of metal hold massive appeal—thanks to their history, design, and in many cases, sheer rarity.
Whether they come from the 19th century or the modern minting era, these coins are true treasures. Let’s break down ten of the most valuable and collectible specimens as of 2025.
1894-S Barber Dime
This coin isn’t just rare—it’s legendary. Only 24 were minted at the San Francisco Mint, and only 9 are known today.
Quick Stats:
- Estimated Value: $2 million+
- Notable Sale: $1,997,500 (2016)
- Rarity: One of the rarest U.S. coins
The mystery behind the 1894-S only adds to its allure. It’s said the Mint director had them struck as gifts for banker friends—and gave three to his daughter. Talk about a smart inheritance.
1916-D Mercury Dime
This was the debut year for the Mercury dime design, and Denver only produced 264,000 of them—an extremely low number.
Quick Stats:
- Estimated Value: $200,000+ (in top condition)
- Notable Feature: Only Denver-made Mercury dime from 1916
With its classic winged Liberty design and ultra-low mintage, the 1916-D remains one of the most desirable 20th-century coins.
1975 No-S Roosevelt Dime
This dime was meant to be struck with an “S” mintmark for San Francisco proofs—but two examples weren’t.
Quick Stats:
- Estimated Value: Up to $456,000
- Known Examples: Only 2
- Notable Sale: $456,000 in 2019
This is one of the rarest modern proof coins ever made—an accidental masterpiece.
1942/1 Mercury Dime
A visible “1” under the “2” in the date makes this overdate error a must-have.
Quick Stats:
- Estimated Value: $500 – $10,000+
- Feature: “2” stamped over a “1”
It’s not ultra-rare, but it is in high demand, especially in well-preserved condition.
1968 No-S Roosevelt Dime
Like its 1975 cousin, this proof dime lacks the “S” mintmark. Only 12 to 15 examples are known.
Quick Stats:
- Estimated Value: $10,000 – $20,000
- Feature: No “S” on a proof coin
This small error equals big value for collectors of modern coins.
1976-S Silver Proof Bicentennial Quarter
Minted to celebrate 200 years of U.S. independence, this 40% silver proof quarter is far more valuable than its clad counterparts.
Quick Stats:
- Estimated Value: Up to $19,200
- Notable Sale: MS70 example sold for $19,200
- Composition: 40% silver
Perfect condition is key—MS70 examples fetch the highest prices.
1976 Bicentennial Quarter Double Die Obverse
A double die error creates a doubling effect on the coin’s design—most notably in the lettering.
Quick Stats:
- Estimated Value: $100 – $1,000+
- Rarity: Uncommon
- Feature: Doubled letters on the front
The error is subtle but profitable. The stronger the doubling, the higher the value.
1976 Bicentennial Kennedy Half Dollar No-S Proof
Here’s another San Francisco goof. This silver proof half dollar missed the “S” mintmark altogether.
Quick Stats:
- Estimated Value: $10,000 – $20,000
- Rarity: Extremely rare
Like other No-S errors, this one is incredibly hard to find and commands big dollars.
1976 Eisenhower Dollar Type 2
The Type 2 Eisenhower dollar has thinner, sharper reverse lettering, making it a standout among Bicentennial dollars.
Quick Stats:
- Estimated Value: $50 – $1,000+
- Feature: Sharper lettering on the reverse
This isn’t a mint error but rather a design variety—still sought after in top condition.
1976-D Bicentennial Quarter on Dime Planchet
A quarter die struck on a dime planchet? That’s a recipe for a rare error.
Quick Stats:
- Estimated Value: $5,000 – $10,000+
- Rarity: Extremely rare
- Feature: Smaller than a quarter with partial design
It’s a hybrid error that shows how something small can become a very big deal.
These dimes and Bicentennial coins represent more than just pocket change—they’re rare artifacts that blend art, history, and a little bit of mint-made magic. Whether you’re a serious collector or just getting started, keep an eye out. Even a tiny dime could change your fortune.
