Using Rewardhero lost and found service in the matter of unclaimed money never happened so far. Offcourse we had some cases when people found the wallet with the money in it. But there was always some ID included, or Rewardhero label attached, so we always new who the money belongs to.
Offcourse the first think when you find some money is that you can keep it because money has no way to be traced or identified as someone belongings. In some rare cases someone leaves some kind of trace on the money bill like a signature or a phone number, but beside that money belongs to us all.
Ok .. so what to do if you find money. Be honest, take it to the police station. They will question you and take your contact information, and if no one claims the money, than the money belongs to you.
