I don't have a personal wallet story, but you reminded me of one that happened while out bow hunting with some friends. This guy with us had two small bucks come right up to him while he was sitting behind a tree that he didn't want to shoot. Too small. Behind them was a good buck that he did want to shoot, but couldn't get a clear shot at because of the small bucks. He looked around, but couldn't find anything to toss at them, so he tossed his wallet at them. It worked, except it scared off all of the deer.
He then spent the rest of the morning trying to find his wallet. It was camoflage. At noon, we all met up and he told us the story, so the four of us went to where he was and tried to find it. We never did. It just totally vanished!!!
