Most people think coins are only worth their face value, but some rare dimes and quarters are worth thousands—or even millions—of dollars. Coin collecting isn’t just a hobby; it’s a treasure hunt.
Some rare coins still circulate today, hiding in pocket change or old collections. One of the most exciting finds is the 1976 Bicentennial Quarter, with rare versions valued at up to $90 million!
Let’s explore some of the most valuable dimes and quarters you might come across.
1916-D Mercury Dime
The 1916-D Mercury Dime is one of the most famous rare dimes, with only 264,000 ever made. This is an extremely low number for a coin meant for everyday use, making it highly sought after by collectors.
Why Is It Valuable?
- Low Mintage – Fewer than 300,000 were made, a tiny number compared to other dimes.
- Iconic Design – Features a winged Liberty head, symbolizing freedom of thought.
- Historical Significance – One of the earliest dimes in the Mercury series.
| Coin | Mint Year | Mintmark | Estimated Value |
|---|---|---|---|
| 1916-D Mercury Dime | 1916 | D (Denver) | Up to $100,000+ |
A well-preserved 1916-D Mercury Dime could turn an ordinary coin collection into a goldmine.
1894-S Barber Dime
The 1894-S Barber Dime is one of the rarest and most valuable U.S. coins, with only 24 ever produced. Today, only nine are known to exist.
Why Is It Valuable?
- Extremely Rare – With only a handful left, it’s a collector’s dream.
- Designed by Charles Barber – The Chief Engraver of the U.S. Mint.
- Historic Status – Considered one of the “Holy Grails” of coin collecting.
| Coin | Mint Year | Mintmark | Estimated Value |
|---|---|---|---|
| 1894-S Barber Dime | 1894 | S (San Francisco) | Over $1 Million |
If you ever find one, you’ve essentially won the numismatic lottery.
1975 No-S Roosevelt Dime
The 1975 No-S Roosevelt Dime is a modern rarity, created due to a minting error where the San Francisco Mint forgot to add its “S” mintmark.
Why Is It Valuable?
- Minting Error – Missing mintmark makes this coin extremely rare.
- Mostly Removed – Most were caught before release, but a few slipped into circulation.
| Coin | Mint Year | Mintmark | Estimated Value |
|---|---|---|---|
| 1975 No-S Roosevelt Dime | 1975 | No Mintmark | Up to $500,000+ |
If you find one, hold onto it—it could be worth a small fortune!
1976 Bicentennial Quarter
The 1976 Bicentennial Quarter was minted to celebrate 200 years of American independence. While most are common, certain rare versions are worth up to $90 million.
Why Is It Valuable?
- Special Design – Features a colonial drummer boy instead of the usual eagle.
- Rare Minting Errors – Some have missing mintmarks, double dies, or silver compositions.
- Limited Edition – Only minted in 1975 and 1976.

1942-D Mercury Dime Overdate
The 1942-D Mercury Dime Overdate is a famous minting error where the number “2” was stamped over a “1.”
Why Is It Valuable?
- Overdate Mistake – A clear “2” stamped over a “1” makes this coin unique.
- High Demand – Collectors pay thousands for well-preserved versions.
| Coin | Mint Year | Mintmark | Estimated Value |
|---|---|---|---|
| 1942-D Overdate Mercury Dime | 1942 | D (Denver) | Up to $20,000+ |
Always check the date on your Mercury Dimes—this small detail could mean a big payday.
