I'v been putting some thought into an answer but I really don't know. I can answer what I think you could have done or what I think I might have done but not what you should have done. Whether it's very likely, or somewhat likely or not likely at all is supposition. But one thing for sure is that by keeping the money, it's 100% guaranteed that the original owner won't get it back. Sorry for bringing up a sensitive subject. I was going to preface my question with "I probably shouldn't post this but..." But that was the first thing that came to mind when I saw Velvet's question.
