Talking of finding money. I remember once in Gibraltar, I was with my husband and being closer to the ground, I found a 20 euros note. I bought a leather bag with it. Once, at home, at the train station, I found 20pounds note. Naive, I asked around if it was theirs and someone took it. I also find about once a year fivers, just by walking down the road. I have an eagle eye, which is very good for finding books lost in the library where I work.
Once I left my wallet at a paid phone (early 90's, it was) and I was really lucky, as it was picked up by someone honest who took the pain to find inside my home number and rang to my sister. I came back after my sibbling went to pick it up for me. She once find the equivalent of a 50 pounds note in the street and gave a tenner to a homeless person.
