Often we ignore the loose coins in our pockets – we move ahead considering them as trivial. But have you ever thought that one of those coins can change your fate? Yes, some such rare dimes and bicentennial quarter coins are still in circulation in America, which can be worth up to $10 million (about Rs 83 crore). This article is about five such amazing coins which may still be present with people or in the market.
Hidden treasure of old coins
We frequently assume that old coins are simply remnants of the past when we see them, but the truth is far more fascinating. These coins’ rarity, condition, errors, and historical significance all affect their value in addition to their metal content. They can occasionally become invaluable due to a minor error made by the mint.
Let us tell you about five rare coins whose prices will surprise you if you’re wondering which ones have the potential to be worth crores.
1. 1894-S Barber Dime – A priceless piece of history

What’s unique: In 1894, the San Francisco Mint produced just 24 coins. Today, there are thought to be ten or fewer. Because this coin is so uncommon, collectors compete for it whenever it is put up for auction.
The estimated value is around $2 million, or roughly ₹16.6 crore.
2. 1975 No-S Roosevelt Dime – The Mistake That Made It Priceless

What’s Unique: Some Roosevelt dimes without the “S” mark were inadvertently released by the San Francisco Mint in 1975. They were extremely rare and valuable due to a minting error.
The estimated value is between ₹500,000 and ₹2 million (₹4.1 crore).
3. 1916-D Mercury Dime – First Look, Low Production

What’s Unique: The Denver Mint produced just 264,000 Mercury Dime coins when they were first introduced in 1916. In terms of mintage, this figure was incredibly low. As a result, its value soars even now if it is discovered in good condition.
Up to $1 million (₹8.3 crores) is the estimated value.
4. 1976 Bicentennial Quarter – A flawed memory of freedom

What’s unique: Although the design of these coins commemorating America’s 200th anniversary was similar, some proof versions (silver proof) were also produced with incorrect metal or printing mistakes. The price of such a coin can reach several million dollars if it is discovered in good condition and the error is proven.
Up to $3 million (₹25 crore) is the estimated value.
5. 1942/41 Mercury Dime – A confluence of two years

What’s unique: What makes this coin unique is that it was produced when a 1941 die was inadvertently stamped with a 1942 mint mark. As a result, the coin appears to have dates from two years at once due to an overdate error. Such mistakes are adored by collectors.
Up to $1.5 million (₹12.4 crore) is the estimated value.
