You are so bound to forget which book its in then boom its donated. A person put 18 100 dollar savings bonds in a book then guess what that book got donated. Putting money in a book is one of the worst things one can do. At least the person who found it is honest and wants to find the owner of the bonds. article Also money should not be used as a bookmark, bookmarks get lost so what do you think will happen with money as a bookmark. Sheesh. Of course no one on GT would do this.
