BOOKS
Some books on your bookshelves might be hidden treasures, sought out for their interesting titles and first editions. To estimate a book’s values correctly, there are plenty of online resources you could use. For example, AbeBooks allows you to search by author, title, or ISBN number. Of course, the rarer the book, the higher its value.
To have a better idea of a book’s worth, AbeBooks is selling a signed first edition of Ken Kesey’s “One Flew Over the Cuckoo’s Nest” for $12,500.
