I was helping my friends kids do a park clean up and one of them found a large wad of cash (less than $200). I told the one who found it that I need to check with the police before she can have it, just in case it belongs to someone in need.

But is that a thing? I didn’t want to say she could keep it right away because I want to set a good example. But it isn’t a ton of money so I assume the police would not be interested. So what do?
