It has just been revealed that a rare type of quarter from 1970 could be worth as much as $35,000!

It seems that some of the quarters made in this year have a mistake on them that makes them very valuable to collectors.

The valuable quarters were minted over 1941 Canadian quarters, which means they feature a very small “1941” on the back of the coin, also known as the tails side.

Coin expert Mike Byers explained that this is a proof quarter, which means it was a test piece.

“Proof coins are struck by technicians who hand feed the blanks into special presses,” he said.

“They are produced, examined and packaged using extreme quality control. It is very unusual to find major proof errors. A few broadstrikes, off-centers, double strikes in collars and off-metals have been known to be found in sealed proof sets.”

“Proof errors are aggressively sought after by many error collectors,” Byers added, explaining why the coin is worth so much.

Byers himself owns one of these quarters after purchasing it at a California auction.

“There is a significant amount of detail on both sides showing the design of the Canadian Quarter,” he said of the coin.

“This is one of the most fascinating and intriguing proof mint errors ever discovered.”

Byers is the author of a book called “World’s Greatest Mint Errors,” which is worth checking out if you’re curious about flawed coins.

In the meantime, it might be worth going through your couch to see if you have one of these flawed coins yourself!
