Some weeks I find five cents and other weeks I find anywhere from $1 to $20. I've been doing it for the last decade, and I'd say I average about $35 a year. It all depends on the weather and where you go.
The more commercial streets are more likely to have money on them. And if it's a windy day you have a much greater chance of finding bills, because they get blown away from people. One windy day, I found a $20 right next to a gas station.
One of the places where I find the most loose change is in parking lots, because people are always fishing for their keys or they get distracted by their cell phones. So a lot of times they'll end up dropping lots of change on the ground.
I tell people that taking these walks help my 401(k) in terms of my health and in terms of my wallet. And the best part about all of this is it's tax-free -- so finding one penny is actually like finding two.
