Let’s know about the five most valuable and rare dimes, which have been valued up to $75 million.
1. 1894-S Barber Dime: The Holy Grail of Coin Collectors
The 1894-S Barber Dime is considered to be the rarest and most valuable coin in the world of coin collectors. It was made at the San Francisco Mint and only 24 coins were minted. Only 9 coins exist today.
The unique story of this coin
It is believed that San Francisco Mint Superintendent J. Daggett had it minted in a special run. He gifted some of these coins to his daughter. There is also an anecdote that his daughter spent one of these rare coins to buy ice cream. It may have been the most expensive ice cream in the world!
Current price
If this coin is in excellent condition, it can sell for up to $1.9 million. Coins in normal condition can also be worth several hundred thousand dollars. In 2007, an 1894-S Barber dime sold for $1.3 million, making it the most valuable dime ever.
2. 1916-D Mercury Dime: The Magic of a Rare Mint Mark
The 1916-D Mercury dime is particularly coveted by collectors because of its design and rarity. It was designed by famous designer Adolph A. Weinman. The dime has a portrait of the Roman god Mercury engraved on it, but it is actually a depiction of Liberty, wearing a winged hat.
Why is its rarity special?
This coin was made at the Denver Mint, but only 264,000 coins were minted. This number is very low, and most of the coins have deteriorated over time, making it more difficult to find coins in good condition.
How much can this coin be worth?
If this coin is in excellent condition, it can sell for $50,000 to $125,000. Even coins in poor condition sell for thousands of dollars.
3. 1942/1 Overdate Mercury Dime: A Mistake That Made It Priceless
Sometimes the mistake in minting coins is what makes them most valuable. The 1942/1 Overdate Mercury Dime is an example of this.
How did this mistake happen?
During the design of the coin in 1942, the old year (1941) numeral was accidentally left below the new year (1942) numeral. This small minting error made this coin extremely rare.
How much can it be worth?
This coin can be worth anywhere from $3,500 to $40,000, and if the coin is in excellent condition, it can be worth even more.
4. 1975 No-S Roosevelt Dime: An Amazing Proof Error
This coin is one of those rare coins that were made by mistake and should never have existed. The 1975 No-S Roosevelt Dime was made without a mint mark, and this makes it even more rare.
Why is its rarity special?
Proof coins are made specifically for collectors and always have a mint mark. But by mistake, some coins were made without the “S” mark (San Francisco Mint), making this coin rare.
What is its current price?
If this coin is in excellent condition, it can fetch a price of $350,000 to $450,000.
5. 1968 No-S Roosevelt Dime: Another Mysterious Mint Mark Mistake
This coin was created due to a minting error, just like the 1975 No-S Roosevelt dime, and it is also very popular among coin collectors.
Why is this coin so unique?
Proof coins are always minted with a mint mark, but some 1968 coins were minted without the “S” mark. This was a major mistake, making this coin extremely rare.
What could this coin be worth?
This coin could be worth anywhere from $25,000 to $125,000, and would be a great find for any collector.
