You may want to look at your change closely because you could have one of these and not even know it.

If you come across a 1970's quarter flip it over and look at the back of it because a certain number of them have a tiny misprint which makes them very valuable.

What you are looking for on the back of the quarter is a tiny 1941 marking that appears above the word dollar.

According to Good Housekeeping, the mistake happened when the quarters were printed over 1941 Canadian quarters. Now you may need a little help seeing the misprint, so break out that magnifying glass.

If you are lucky enough to find one of these misprinted quarters it could be worth more than $35,000.

A few people have already found one of these coins and put them up on Ebay for sale with bids topping $35,000 and over 300 people intrested in the coins.
