The world of rare coins is fascinating, particularly when everyday currency turns out to be worth millions of dollars.
Although most people think of coins as simple forms of money, certain rare specimens can fetch incredible prices at auction due to their uniqueness, historical significance, or minting errors.
Among the most extraordinary finds are eight rare dimes and the rare Bicentennial quarter, each potentially worth up to $70 million. Yes, you read that correctly—these coins could be hiding in your pocket change, waiting to make you a fortune.
In this blog, we’ll take a deep dive into the eight rare dimes and the Bicentennial quarter that have taken the numismatic world by storm.
From their origins and unique characteristics to how you can spot these coins, we’ll explore what makes them so valuable and why they continue to capture the attention of collectors.
What Makes a Coin Rare?
A coin’s rarity is determined by several factors:
- Mintage Numbers: Coins that were produced in small quantities or those that were removed from circulation or melted down have higher value.
- Minting Errors: Coins with flaws such as wrong designs, misplaced letters, or incorrect mint marks are considered mistakes—and can be worth much more than their face value.
- Historical Significance: Coins tied to important events or historical periods tend to gain value over time.
- Condition: Coins in pristine condition are always more valuable than those that are worn out or damaged.
Now, let’s explore the coins that have made their way into the rarified air of $70 million valuation.
8 Rare Dimes Worth $70 Million Each
The dime, worth 10 cents, is one of the most commonly circulated coins in the United States. However, despite its modest face value, certain dimes have been discovered to be extraordinarily rare and immensely valuable. Let’s take a look at these dimes.
1. 1894-S Barber Dime
The 1894-S Barber Dime is one of the rarest and most valuable dimes in U.S. history. Only 24 coins were minted, and fewer than a dozen are believed to still exist. What makes this coin so desirable is its extreme rarity and pristine condition.
One of these dimes sold for a jaw-dropping $1.9 million in 2007, and experts estimate it could fetch even more today due to its rarity and the increasing demand from collectors.
2. 1916-D Mercury Dime
The 1916-D Mercury Dime is a favorite among collectors, as only 264,000 were minted. The design of the coin, featuring a winged Liberty head, is highly regarded.
Due to its low mintage, the 1916-D Mercury Dime can be worth well over $500,000 depending on its condition. A flawless specimen could fetch as much as $7 million.
3. 1942/1 Mercury Dime
The 1942/1 Mercury Dime features a minting error, with the “1” being partially struck over a “2” from the year before.
This rare error coin is highly sought after by collectors. Only a few hundred examples exist, and an error-free coin in near-perfect condition has been known to sell for up to $2 million.
4. 1919-D Mercury Dime
The 1919-D Mercury Dime is another highly collectible coin, with an estimated mintage of just 1.5 million.
While not as rare as the other dimes on this list, it is still valuable due to its low mintage and the fact that many were worn out or damaged. It is possible to see auction prices around $2.5 million for a well-preserved example.
5. 1945 Micro S Mercury Dime
The 1945 Micro S Mercury Dime is a unique error coin in which the mintmark “S” is much smaller than usual. This difference makes it an extremely sought-after piece for collectors, with one example fetching over $3 million in the past.
6. 1931-S Mercury Dime
Another Mercury Dime that’s highly prized is the 1931-S Mercury Dime. With a mintage of only 1.2 million coins, this coin is difficult to find in pristine condition.
The scarcity of high-quality examples has pushed its value to well over $500,000, with the rarest coins valued closer to $4 million.
7. 1947-S Roosevelt Dime
While the 1947-S Roosevelt Dime may not be as famous as other dimes on this list, it is notable for its low mintage and its high-grade examples. The 1947-S has reached prices of $1.5 million, especially for those that are in mint condition.
8. 1936-D Mercury Dime
The 1936-D Mercury Dime is one of the last of the Mercury series to be produced before the Roosevelt Dimes came into circulation.
With only 1.4 million minted, it’s not as rare as some of the others on this list, but its low production numbers and popularity among collectors have seen its price surge to $5 million for specimens in near-perfect condition.
