Researchers of the paranormal have identified a common theme in ghost tales: dime-dropping ghosts. That is, many people report the belief that ghosts are leaving them dimes. Consider this example reported on about.com's paranormal phenomena blog
My aunt Julie died two years ago, on November 14, 2006. She had three children. Her youngest was only 14. Not long after her death, my uncle (her husband) found a dime on the floor of his workout room. No one, but him goes in that room. It was weird because he never has money when working out! He told my mom about it, and my mom had found a dime too! That same day. She found it at work, in the corner of her office. She called my mom about the stories. She found that very odd because she just found two dimes underneath my pop's chair at the kitchen table. Neither one of them put the dimes there. After almost the whole family found many dimes that were randomly anywhere, we knew it was Aunt Julie.
That's just one example. There are many more. My dead relatives must be stingy because they never leave me any dimes. But if any of them are listening out there, and are feeling generous, please consider leaving more than ten cents! $100 bills would be nice.
