After my mother passed away, a friend told me that she had read about "pennies from Heaven"...and that it meant that someone close to you who had passed was tossing them downward to let you know he/she was thinking of you. Well, I'm not kidding - I started finding pennies everywhere! My mother passed in 2002, and I'm still finding them! I found the penny poem at this website: http://www.geocities.com/jlkangel/pennies.html
The site, itself, is SO sad - it's dedicated to the woman's daughter, who passed away.
