* Condition: Is the book in pristine condition, with no tears, marks, or fading? Or is it worn and damaged?
* Edition: Is it a first edition? A rare printing?
* Binding: Is it hardcover or paperback? What kind of binding?
* Dust jacket: Does it have the original dust jacket? Is it in good condition?
* Signature: Is the book signed by the author or someone else of historical significance?
* Rarity: How many copies of that specific edition exist?
To find out the potential value of your book:
1. Look for identifying information: Check the title page for the edition, publisher, and printing date.
2. Assess the condition: Look for any damage or wear and tear.
3. Research online: Use online resources like eBay, Amazon, and Abebooks to see what similar books are selling for.
4. Consult a book appraiser: For a more accurate appraisal, consider contacting a professional book appraiser.
Keep in mind that even a common edition of "The Adventures of Tom Sawyer" from 1965 can be worth a decent amount if it's in excellent condition.
