The 1970-S Washington quarter may seem like just another coin, but certain errors during its minting process can make it incredibly valuable. In fact, some of these error coins have sold for over $500,000 at auctions, making them a treasure for collectors. These mistakes turn an ordinary quarter into something extraordinary, and if you have one in your collection, you could be sitting on a small fortune. Let’s explore the five most surprising errors that can boost the value of the 1970-S quarter.
Double Die Obverse (DDO) Error
A Double Die Obverse (DDO) error happens when the coin’s die is not properly aligned during production. This results in doubled features on the front of the coin, such as the inscriptions “LIBERTY” and “IN GOD WE TRUST”. These doubled details make the coin much more noticeable and valuable to collectors.
Why is it valuable?
Coins with clear and distinct DDO errors are rare and highly sought after. The 1970-S quarter with a DDO error can be worth far more than a regular quarter, sometimes fetching prices as high as $500,000 or more, depending on the clarity of the doubling and the coin’s condition.
Off-Center Strikes
An off-center strike occurs when the coin blank is not aligned properly during minting. This causes the design to be printed off-center. The extent of this error can vary; some coins may be 10%, 25%, or even 50% off-center.
Why is it valuable?
The value of off-center coins increases with the degree of misalignment. Coins with a larger off-center error, and those in good condition, can sell for significant amounts. These coins are not as common, which makes them more valuable to collectors looking for unique items to add to their collections.
Wrong Planchet Errors
A wrong planchet error occurs when a coin is struck on a blank that was intended for a different denomination. For the 1970-S quarter, this can mean that the coin was mistakenly struck on a dime planchet, which makes it smaller in size and weight compared to a normal quarter.
Why is it valuable?
These coins are rare and highly unusual, making them extremely valuable. Because the planchet was meant for a different coin, the wrong size and weight make these quarters stand out. If you find one of these rare error coins, it could fetch high prices at auction.
Clipped Planchet
A clipped planchet error happens when part of the coin’s blank is missing before the coin is struck. This results in a coin with a missing section. The size of the clip can vary, from a small part to a larger chunk missing.
Why is it valuable?
The value of a clipped planchet quarter depends on the size of the clip and the overall condition of the coin. Though not as common as other errors, clipped planchet coins can be highly valued, especially if the clip is large and the coin is in good shape.
Broad Strike
A broad strike error occurs when the coin is struck without a retaining collar. This results in the metal spreading more than usual, causing the coin to become larger in diameter with a distorted design. The coin will appear wider than a normal quarter.
Why is it valuable?
Broad strike errors are rare and become more valuable the better the condition of the coin. Coins that have a clean, sharp design despite the broad strike error can be worth a lot of money, as collectors seek these unique examples.
