Have you ever thrown something out, like a Rembrandt etching or an old Tiffany lamp, only to find out later it was worth tens of thousands of dollars? Neither have I. Yet every time I watch "Antiques Roadshow" or "Pawn Stars," I hear that someone found this Stradivarius violin in the trash, or that a neighbor had given them George Washington's sword to thank them for cleaning out the attic.It makes me wonder what I did to get the stingy neighbors I have, who never seem to throw out anything valuable. When I go through their trash, there's never anything worth selling, and yet I'm the one who gets yelled at.
