CHICAGO — The year 1970 may be your lucky number.

Check your pockets for a quarter made that year, because it could be worth a lot of money.

The coin is currently listed at $35,000. According to reports, at least 22 people have expressed interested in the coin.

A quarter from 1970 could be worth more — much more — than 25 cents because of a mistake on the back.

On the back — just above the word “dollar” — there is a tiny “1941.”

The mistake happened when the quarters were printed over 1941 Canadian quarters.

“This is one of the most fascinating and intriguing proof mint errors ever discovered,” the listing reads. There are currently more than 300 people interested in the item on eBay.

What should you do if you have a 1970 quarter with a ‘1941’ imprint?  WHNT News 19 talked with a local coin expert to find out how much these quarters could be worth.

One man we spoke with through Walt Bartee Coins and Bullion says the quarter advertised on the eBay posting is likely in mint condition. He said that any coins we carry around in our pockets are ones that have been circulated. That means they’re more beaten up and worn, which in turn means a coin loses its value.

He suggests that if you have a coin with similar markings to the one described above, which is rare, you should have a coin dealer take a look at it.

BBB of North Alabama President Elizabeth Garcia gave us some tips if you choose to sell a rare coin or other item of high value:

  • Get 3 appraisals for estimates of the item’s value
  • If you have anything that can prove its authenticity, that will be helpful in a sale
  • If it’s high value, although there may be additional cost involved you may want to consider insuring your item
  • If you plan to sell online, use an established marketplace like Amazon or eBay
  • Don’t allow a buyer to finish the transaction offline. Always stay on an established marketplace for the whole transaction
  • If you’re selling an item in-person, accept a cashier’s check or cash. The goal is to get a verified payment, so don’t accept a regular check
