The Legendary $35,000 Mint Error

How much is 1970 quarter worth as the most expensive example? One of the most interesting stories in coin collecting revolves around a 1970 quarter worth $35,000. This isn't valuable due to its age or metal content but because of a mint error that makes it one of a kind.

This rare 1970 error quarter was discovered by Mike Byers, a renowned expert in mint error coins. Byers has an impressive reputation, having authored several books on the subject and consulted with major certification companies to authenticate error pieces. When he listed this coin on eBay with an asking price of $35,000, it caused quite a stir in the collecting area.

The coin in question is a 1970-S Proof Washington quarter that was accidentally struck over a 1941 Canadian quarter. Under magnification, you can see traces of the Canadian coin's design beneath the U.S. features—an overlap that shouldn't have been possible under normal minting procedures.

The State Auction and Legal Ownership

This was from a collection auctioned by the State of California. Before the auction, the U.S. Secret Service inspected the collection to make sure that all items were legal to own. They cleared it, and the collection was sold to the public. 

But how did a 1941 Canadian quarter find its way into the U.S. Mint nearly three decades later? And why is a 1970 quarter worth $35000? The U.S. Mint doesn't produce Canadian currency, and the stringent controls in place make such an error seem improbable. Some experts suggest that an insider at the San Francisco Mint may have intentionally placed the foreign coin into the minting process. This theory is supported by the existence of other unusual coins from the same period and facility, e.g., a quarter struck on a 1900 Barber quarter and another on a Philippine twenty-five centavos piece.

While the exact circumstances remain a mystery, what is certain is that this coin's characteristics make it highly desirable among collectors of U.S. errors.

Other Notable Errors in the Quarter 1970 Series

Is a 1970 quarter worth anything if it has other misprints? The 1970 quarter error list includes several other anomalies:

  • Double Die Errors: Where the design elements appear doubled due to a misalignment during the striking process.

  • Off-Center Strikes: Coins not properly centered during minting, resulting in missing details on one side.

  • Clipped Planchets: Coins with a portion missing because the metal blank wasn't properly cut.

  • 1970 D Quarter Errors: Specific errors from the Denver Mint, e.g., die cracks and irregularities.

These 1970 quarter misprint examples can increase the value of a 1970 quarter a lot. Sometimes it can reach hundreds or even thousands of dollars, but it depends on the rarity and condition.

The Value of Mint Marks: No Mint Mark, "D," and "S"

1970 Quarter with No Mint Mark (Philadelphia Mint)

Typically, the 1970 no mint mark quarter value is equal to the face value in circulated condition. However, uncirculated examples or those with errors can be more valuable.

High-grade specimens without a mint mark can be sought after by collectors looking to complete a set.

By the way, you can also come across ‘1970 P quarter value’ requests. It is the same point, as P means Philadelphia. 

1970 Quarter D (Denver Mint)

Standard circulated 1970 quarter value D is usually worth 25 cents, but those with errors or in mint condition can be worth more.

The 1970 D quarter error coins, such as those with off-center strikes or die anomalies, can increase the value significantly.

1970 S Quarter (San Francisco Mint)

Proof coins from the San Francisco Mint are typically more valuable due to their limited mintage and higher quality. 1970 S quarter value may be from a few dollars to much more if they have errors.

Proof coins are highly desirable among collectors for their sharp details and mirror-like finishes.
