It's time to look for loose change because some quarters produced in 1970 might be worth a pretty penny.
A certain number of quarters produced in 1970 have a tiny misprint which makes them very valuable.
According to Good Housekeeping magazine, the coins were printed over 1941 Canadian quarters and therefore a tiny "1941" marking appears above the word "dollar" on the back of the coin.
It's almost impossible to see without a little help, however bids for the coin with the mistake have topped more than $35,000 on eBay.
It's not clear how many coins actually have the mistake, so check your wallet and under your sofa cushions.
