Bicentennial quarters, minted in 1976 to commemorate the 200th anniversary of the United States’ Declaration of Independence, have become iconic for coin collectors. These quarters aren’t just a nod to American history—they also hold incredible value due to unique minting errors.
Some of these coins are valued at a jaw-dropping $20 million, while others are worth over $950,000. Let’s look into these rare and valuable Bicentennial quarters and what makes each one so special.

Double Die
The Double Die Obverse quarter is a collector’s dream, valued at an astonishing $20 million. This coin has a distinct doubling effect on the date and the phrase “IN GOD WE TRUST,” caused by a minting error. The duplicated design makes this coin incredibly rare and highly desirable.
Off-Center
Another prized Bicentennial quarter, valued at $20 million, is the Off-Center Strike quarter. This coin was struck when the coin blank was misaligned, leading to an off-center design. These types of errors are extremely rare, making them highly valuable to collectors.
Overstruck
This rare overstruck quarter, valued at $20 million, was mistakenly struck on a 1941 Canadian quarter. The resulting blend of designs from two different coins makes this a unique and one-of-a-kind collector’s item that’s highly sought after.
Silver
Valued at $20 million, the Silver Composition quarter is another rare gem. In 1976, some Bicentennial quarters were mistakenly minted using silver, a material that hadn’t been used for quarters since 1964. This error significantly increased the coin’s value, making it a prized possession for collectors.
No S Proof
Most proof coins from the San Francisco mint bear an ‘S’ mintmark. However, some Bicentennial quarters were minted without this mark, leading to the creation of the rare No S Proof quarter. This unusual omission has raised the value of this coin to $20 million.
Broadstruck
The Broadstruck quarter, worth $20 million, is another fascinating error coin. When a coin is struck outside its retaining collar, it leads to a broader, misshapen result. This rare error makes this coin incredibly valuable to collectors.
Clipped Planchet
Valued at $20 million, the Clipped Planchet quarter has a portion of the coin missing due to a minting error. The metal sheet was improperly fed during production, resulting in a clipped edge. This unique error enhances its value in the eyes of collectors.
Partial Collar
Another error coin worth $20 million is the Partial Collar Strike quarter. This quarter has a misaligned edge due to an incomplete striking process. The thicker edge on one side gives this coin a distinct appearance, making it highly collectible.
Multi-Struck
The Multi-Struck quarter, valued at $20 million, is an example of an error where the coin was struck multiple times by the minting press. This error results in a distorted, overlapped design, making each coin uniquely flawed and highly valuable.
1975 Dated
Although not valued at $20 million, the 1975 Dated quarter is still worth over $950,000. No quarters were supposed to bear the year 1975, as they were all meant to be dated 1776-1976. This rare anomaly makes the coin a valuable find for collectors.
Misaligned Die
Valued at over $950,000, the Misaligned Die quarter features a design shift due to a misaligned die during the minting process. This minting error results in a distinctive look, making the coin a rare and valuable collectible.
Double Struck
Another rare quarter valued at over $950,000 is the Double Struck quarter. The coin was struck twice, with the second strike being off-center. This error gives the coin a unique and visually striking appearance, making it highly sought after by collectors.
Wrong Planchet
The Struck on Wrong Planchet quarter, valued at over $950,000, was mistakenly minted on a planchet intended for another type of coin. This rare minting error adds to its value and desirability among coin enthusiasts.
Struck Through
This Struck Through Error quarter, worth over $950,000, had a foreign object between the die and the planchet during striking. The result is a distinctive imprint on the coin that collectors find highly valuable.
Foreign Overstrike
Valued at over $950,000, the Overstruck on a Foreign Coin quarter is another fascinating example of a minting error. This coin was struck over a foreign coin, creating a blend of two different currencies, which makes it a rare and highly valuable piece.
