I write a new book on the History of Ducks Unlimited. I donate the copyright for the book to Ducks Unlimited (a public charity). A qualified appraisal indicates that the copyright is worth $50,000. My cost basis in creating the book was only about $50 worth of paper and ink. How much can I deduct for this gift? + a share of revenue from the copyright for the next 12 years $50,000 + a share of revenue from the copyright for the next 12 years
