Imagine reaching into your pocket and pulling out a coin that’s worth millions! It sounds unbelievable, but for some lucky collectors, it’s already a reality. The 1969-S dime, 1970-S dime, and Bicentennial quarter are some of the rarest coins in the world, with prices that can reach up to $19 million.
These coins are worth so much because of their rarity, historical significance, and unique minting errors. If you’re a coin collector or want to know why these coins are worth so much, this guide will tell you why these dimes and quarters are so special.
Bicentennial Quarter

The Bicentennial quarter was released in 1976 to commemorate the 200th anniversary of the United States. It differs from regular quarters because it features an image of a drummer boy playing drums on the reverse and a picture of Independence Hall on the obverse.
Why is it worth so much?
Although most Bicentennial quarters are common and worth only their face value, some rare versions can be worth millions. This is due to certain minting errors, such as:
- Missing mint mark
- Double strike (the design is printed twice)
- Off-center design (the design is not printed correctly)
Some coins with these rare errors have sold for as much as $19 million, proving that sometimes even common coins can become valuable treasures for collectors.
1969-S Dime
The 1969-S dime, produced by the San Francisco Mint, is considered one of the rarest dimes. This coin became famous due to a double-die error, which is a mistake in which certain design elements appear twice on a coin.
Why is it so rare?
- Double-die obverse error – The design of this coin appears to be slightly double printed, making it unique.
- Limited availability – Very few such coins have been identified.
- High value – If this coin is found in excellent condition, it can be worth up to $19 million.
Surprisingly, this coin has been found by some people in normal transactions, proving that sometimes rare coins can come into our pockets unknowingly.
1970-S Dime
There is a lot of mystery surrounding the 1970-S dime. Some experts believe that this coin was never officially released, which further increases its rarity.
What makes it special?

- Extremely limited production – It is believed that very few versions of this coin ever came into circulation.
- Uncertain origin – Some numismatists believe that this coin was part of an experimental batch.
- Highly Valuable – It has been valued at up to $19 million due to its rarity.
Collectors who own this coin consider it one of history’s unsolved mysteries. Its mysterious origins and extremely limited number have made it one of the most sought-after coins in the world.

Even though the chances of finding a 1969-S dime, a 1970-S dime, or the rare Bicentennial quarter are very low, these coins are still in existence today.
