The world of rare coin collecting is full of surprises, and the 1970-S quarter is a shining example. Known for its unique errors, this coin has become a hot topic among numismatists. Some error variants of the 1970-S quarter have fetched over $500,000 at auctions! But what makes these coins so valuable? Let’s dive into the top five errors that turn a 1970-S quarter into a treasure.
1. Double Die Obverse (DDO) Error
One of the most sought-after errors in any coin is the Double Die Obverse. This occurs when the coin’s die is misaligned during production, resulting in doubled elements on the coin’s front. On the 1970-S quarter, doubling is most noticeable in the lettering, such as “LIBERTY” and “IN GOD WE TRUST.” Sharp-eyed collectors are willing to pay a premium for a clear and distinct DDO error.
2. Off-Center Strikes
Off-center strikes happen when the coin blank isn’t properly aligned during the minting process. For the 1970-S quarter, this error is particularly intriguing because it disrupts the iconic Washington design. Depending on how far off-center the strike is—10%, 25%, or even 50%—the value can vary. A well-preserved off-center 1970-S quarter can sell for tens of thousands of dollars.
3. Wrong Planchet Errors
Imagine finding a quarter that doesn’t feel or look right. This could be a wrong planchet error, where the quarter is struck on a blank meant for a different coin, such as a dime or foreign currency. For the 1970-S quarter, errors struck on smaller or foreign planchets are rare and highly collectible. Some of these coins have fetched six figures due to their rarity.
4. Clipped Planchet Errors
Another intriguing error is the clipped planchet, which occurs when the coin blank is improperly cut, leaving a visible “bite” out of the quarter. For 1970-S quarters, clipped planchet errors are relatively uncommon, making them highly desirable to collectors. The cleaner and more pronounced the clip, the higher the coin’s value.
5. Proof Coins with Mint Errors
The 1970-S quarter was part of a special proof set, designed for collectors. However, even proof coins weren’t immune to errors. Some proof 1970-S quarters show anomalies like die cracks, incomplete strikes, or double images. These mint errors on proof coins are especially valuable because they’re considered production anomalies in an otherwise pristine batch.
Conclusion: A Coin Worth Hunting For
The 1970-S quarter proves that mistakes can lead to incredible value. Whether it’s a double die obverse or a wrong planchet error, each variant tells a story of minting mishaps and rarity. If you have a 1970-S quarter, it might be worth examining closely—you could be holding a piece worth $500k or more.
