Most people in the US use 10 paise or quarter (25 cents) coins for everyday transactions. But did you know that among these common coins, there are some coins that are so rare and priceless that they are estimated to be worth about $23 million (about Rs 190 crore)?
Surprisingly, 6 such extremely rare coins, out of which 5 are 10 paise and 1 quarter, are still being used in normal transactions. These coins are passing through the hands of people unknowingly—just waiting for an aware person to identify them.
Let us understand these priceless coins in a little detail:
1. 1894-S Barber Dime – The King of Rarity
Only 24 Barber dimes were minted at the San Francisco Mint in 1894. Today, only 9 of them exist, and it is believed that one coin is still circulating among the general public.
The special thing about this coin is that it was made by Mint Superintendent John Daggett for a special purpose. He gave three coins to his daughter Hallie, but she spent one coin to buy ice cream! Today, that ice cream might have become the most expensive in the world.
Identification of this coin: Picture of Lady Liberty on the front and “S” mintmark on the back.
Price: In good condition, this coin can sell for about $23 million.
2. 1916 Double-Die Mercury Dime – Unknown mistake, priceless treasure

When the Mercury Dime series started in 1916, a big mistake was made. The design on the coin was printed in double image due to a die error – especially on the date and Lady Liberty’s face.
No one understood this mistake at that time, but when it was discovered later, it was found that perhaps only 15-20 coins were made with this mistake.
To date, only 3 coins have been officially certified. And one may still be lurking in normal circulation.
Value: $23 million in perfect condition, millions in poor condition.
3. The 1975 No-S Proof Dime – That Wasn’t Meant to Be
Proof dimes minted in 1975 were supposed to have an “S” mintmark, since they were produced in San Francisco. But some coins were accidentally printed without a mintmark.
These coins were part of proof sets made specifically for collectors. Such an error is technically impossible since proof coins are quality-checked multiple times.
Only 2 coins have been certified so far. One coin may still be in circulation.
Value: One was worth $516,000 in 2019. Today, it is believed to be worth up to $23 million.
4. 1942 “Copper” Experimental Dime – Wartime Secret
During World War II, the US began experimenting with alternative metals for coins because metals like silver were needed for war purposes.
- A few copper dimes were made for testing during this time, but all were officially destroyed.
- However, at least 3 of the coins ever came out – one of which was found in a bank roll in 1959.
Color: These coins are a slightly reddish-brown color than normal dimes.
Value: About $23 million due to historical significance and rarity.
5. 1964 Special Strike Dime – A Sign of Change
In 1965, the US began minting clad (cheaper metal alloy) coins instead of silver. Prior to this, a few special Special Strike dimes were minted in 1964.
These were neither normal coins nor proof coins. These have a special finishing, shiny surface and clean design.
Only 5 such coins are known to exist, one of which may have reached common use.
Value: These coins depicting this historic moment of change are believed to be worth $23 million.
6. 1976 Silver-Clad Bicentennial Quarter – A Unique Combination
In 1976, some 40% silver quarters were made for the 200th anniversary of the US, but they were only for collectors and all had an “S” mintmark.
But later some quarters were accidentally made on silver metal without a mintmark – which is technically impossible.
Such coins are extremely rare and at least two coins are known, one of which may still be circulating among people today.
Value: Up to $23 million due to silver composition and historical significance.
