It’s easy to overlook the coins jingling in your pocket, but some of those everyday dimes and quarters might just be worth a small fortune.
Especially fascinating are certain rare dimes and the patriotic Bicentennial quarter — coins that tell stories of minting errors, low production numbers, and historical milestones.
Let’s look into these collectible coins and find out what makes them so valuable.

Mercury
The Mercury dime, minted between 1916 and 1945, is one of the most beloved U.S. coins. Interestingly, it doesn’t show the Roman god Mercury but Liberty wearing a winged cap — symbolizing free thought.
The standout? The 1916-D Mercury dime. Only 264,000 were made in Denver before production pivoted to quarters. Because of its limited release and being a first-year issue, this coin has become a collector’s dream.
If you’ve got one in good condition, it might be worth over $10,000 — and if it’s in top condition, you’re looking at $20,000+.
Overdate
Fast forward to World War II, and another Mercury dime grabs attention: the 1942/1 overdate. What happened here? Basically, a 1941 die was accidentally reused and stamped with a 1942 date — leaving a visible double date.
These dimes were minted in both Philadelphia and Denver. The Philadelphia version is rarer and sells for more, often $5,000 or more depending on condition. It’s a tiny minting mistake that turned into a major win for collectors.
Barber
Before Mercury dimes, the Barber dime series (1892–1916) reigned. Among them, the 1894-S Barber dime is legendary. Why? Only 24 were minted, and just 9 are known to exist today.
The backstory is almost cinematic: John Daggett, the San Francisco Mint Superintendent, supposedly had them minted to balance the books and gave three to his daughter — one of which she allegedly spent on ice cream. Today, if you find one, it could be worth over $1 million.
Roosevelt
Even modern dimes can be gold mines. Enter the 1975 no-S proof Roosevelt dime. These were struck at the San Francisco Mint — but a couple were accidentally released without the “S” mintmark.
Only two examples are known, and they’re considered some of the rarest modern U.S. coins. The last public sale? A whopping $450,000. So yes, check those proof sets carefully.
Bicentennial
Now, let’s talk quarters — specifically the Bicentennial quarter. Minted in 1975 and 1976 to celebrate America’s 200th birthday, these coins have a special reverse design featuring a drummer and a torch surrounded by 13 stars.
While most are common and worth face value, special mint sets (especially silver-clad versions) and high-grade uncirculated examples can fetch higher prices.
Collectors love the history and symbolism, making even regular-looking ones more desirable.
Here’s a quick snapshot of these rare finds:
| Coin | Notable Feature | Est. Value |
|---|---|---|
| 1916-D Mercury Dime | Low mintage, Denver mint | $10,000–$20,000+ |
| 1942/1 Mercury Dime (Phila.) | Overdate error | $5,000+ |
| 1894-S Barber Dime | Only 24 minted | $1 million+ |
| 1975 No-S Roosevelt Dime | Missing mintmark, only 2 made | $450,000+ |
| Bicentennial Quarter (silver) | Commemorative, limited sets | Up to $20+ |
Rare coins prove that even the tiniest treasures can pack big surprises. Whether it’s a dime with a minting error or a quarter made for the nation’s 200th birthday, these coins connect us to history in a pocket-sized package.
So next time you check your change, don’t just count the cents — consider the stories.
