Exercise pays (literally)!

Queen, while we're reminiscing on what parents do with lost change my Dad had an economic theory related to that; he thought that when times were good there was not only more lost change but higher denominations because people would feel it was not worth stopping to pick it up unless it was a paper bill, then quarter, dime, nickel then finally only pennies. The worse the economy was than only pennies were left on the street.

I think your dad was probably right. My mom grew up in the depression so she always picks up coins...even pennies.
