The price of a writer's autograph book varies with many factors, including the popularity of the writer, the quality of the autograph book, the edition and printing time of the book, the appearance and scarcity of the book, etc.

Take the famous writer Jia Pingwa's autograph book as an example, the price may be between 100 yuan and 600 yuan. The specific price depends on the variety and appearance of the autograph book.

Generally speaking, the price of signed books is usually higher than that of ordinary books, but not all signed books have high value. If you want to determine the price of a specific autograph book, you'd better consult a professional or relevant institution.
