I've never lost anything (other than my patience) while at WDW, but I did find something once. I found a wallet. It had five $10.00 bills in it with nothing else. No ID, nothing. Man it was so tempting to just say to myself, I just found some extra spending money for the trip. But, my upbringing jumped out in front of me and I remembered my two girls who were 6 and 8 years old at the time, and decided I needed to set an example, so I gave it to a CM. I couldn't help feeling that it never got any further then the CM, but it wouldn't be fair to assume that. I did wonder, like I would have, if the family that lost that just figured that cash with no ID was probably lost forever. I'm sure someone, possible a youngster, had their trip at least slightly tainted by the loss.
