Selling a rare book

Selling a rare book of 1959 edition. Biography of F.I. Chaliapin. Since the book is more than 60 years old, it is an antique item, because if this or that thing is 50 or more years old, then it becomes antique. The book has over 700 pages with photographs. Over time, the spine was very worn, so I lower the price from 6500 to 4000, but this is final. Ocean region. I rarely go online. It's better to call the mob right away.
