If you find money on a street is it finders keepers?
Most localities the policy is to turn it into the police
department and after so many days (30 most places) if no one claims
it you can pick it back up and keep it..
Most areas you are required by law to turn it into the police,
in other areas you are required by to make a reasonable attempt to
find the owner, such as placing a newspaper classified ad in lost
and found, example found money in parking lot of wally world dept
store, call 656565656 with correct amount to verify ownership.
