2 Rare Dimes and a Bicentennial Quarter: In the world of coins,numismatics, every coin is not just a piece of metal. There are some coins whose story, historical background and errors in manufacturing make them not only special but also worth crores. In this article, we will talk about three such extraordinary American coins which, due to their rarity and uniqueness, have fetched a price of up to $19 million i.e. approximately Rs 150 crore. These coins are: the 1969-S Double Die Dime, the 1970-S Proof Dime ‘No S’ variety, and the 1976 Bicentennial Quarter.
1969-S Double Die Obverse Dime:

Double History, Double Price. This coin was prepared in 1969 at the San Francisco Mint in California. Its most unique feature is its “double die obverse” i.e. repetition of the design made on the front side.
What is this error?
The letters and images printed on the coin such as “LIBERTY”, “IN GOD WE TRUST” and the President’s face are printed twice. This is a minting error that does not occur commonly and is very rare.
Why is it so valuable?
- This coin came into circulation in very limited numbers.
- Only a few certified pieces exist today.
- It is valued at up to $19 million (Rs 150 crores) in good condition.
1970-S Proof Dime – ‘No S’ Variety: A Missed Imprint and Increased Price

In 1970, the San Francisco Mint released special proof sets made only for collectors. But some of these dimes did not have the San Francisco ‘S’ mintmark printed on them.
How did this happen?
It was a machine error – the die that applies the mintmark was not set properly. Due to this, the ‘S’ was missing on some coins, due to which those coins are now considered rare.
Features of this dime:
- Only a few proof dimes were issued without the ‘S’ mark.
- These coins were only in collectors’ sets, so it is almost impossible to get into the hands of the general public.
- This high quality coin has also been sold for up to $19 million.
1976 Bicentennial Quarter: A symbol of patriotism and pride of collection

This quarter, released in 1976 on the occasion of America’s 200th anniversary (Bicentennial), is known for its unique design. There is a colonial drummer on its back, which reflects the country’s revolutionary heritage.
What is special in these quarters?
- These quarters were made in large numbers, but some pieces have been found to have errors such as double die, incorrect mintmark, or missing mintmark.
- These rare error varieties are in high demand.
- Some of these unique varieties have fetched prices as high as $19 million.
