I've written before about the practice of putting pennies on grave sites. Ben Franklin's in Philadelphia, PA, makes sense because of his "A penny saved is a penny earned" quote. And Daniel Chester French's tombstone in Concord, MA, is covered in face-down pennies because he sculpted the Lincoln memorial featured on the coin's reverse. But pennies on John Wilkes Booth's grave? I still can't decide if it's tacky or defiant.
