Many schemes for making extra cash quickly don't deliver what they promise. The only guaranteed way to fatten your wallet without spending too much time or effort is by looking for money you already have. If you want to earn extra cash without leaving home, search for loose change in the places listed below.

According to Wise Bread, the average American has around $90 of unaccounted for coins and bills hidden around the house. Spending an afternoon scouring the nooks and crannies of your belongings can turn up enough cash for a shopping spree—or it can help you pay your bills for the month. Even though the loose change in your home is technically yours to begin with, it doesn't have any value to you if you don't know where it is. Dedicating a few hours to gathering it up can be just as worthwhile as working to earn a paycheck.

Any place you're likely to toss spare change and forget about it is a good place to start. This includes pockets, purses, wallets, and drawers. It also pays to look in spots where money may have gotten lost, such as in your couch cushions, your laundry room, and the floors of your car. Once you've collected a decent chunk of change, you can take it somewhere to convert it to dollar bills. Machines like Coinstar claim a redemption fee, but your bank will process them for free. While you're there, you can deposit your findings into your savings account if you're in a practical mood.
