Is your old book valuable? Learn how to identify first editions, check printing and condition, spot book club editions and value signed and antique books.

Shelves of old books are a staple of estate clearances. Most are worth little, but first editions, early printings, signed copies and antiquarian books can be worth a lot. Here's how to separate them.
Age isn't enough
Many old books were printed in large numbers. Value depends on demand, edition, condition and rarity.
First editions and printings
Collectors usually want the first edition, first printing. Check the copyright page:
- Statements like "First Edition" or "First Printing"
- A number line (e.g. "10 9 8 7 6 5 4 3 2 1") — the lowest number often indicates the printing
- Publisher-specific conventions vary, so check guides
Book club editions
Often smaller, cheaper paper, no price on the dust jacket, and sometimes a small blind stamp on the back board. They generally have little collector value.
The dust jacket
For many 20th-century books, the dust jacket is a huge part of the value. A first edition without its jacket can be worth much less than one with it.
Condition
- Binding tight and intact
- No missing pages or plates
- Minimal foxing (brown spots), water damage, writing or library stamps
- Original covers and spine
Signed and inscribed books
Author signatures can add significant value, especially with provenance.
Antiquarian books
Early printed books, fine bindings, illustrated plate books, maps and atlases have their own market. Check whether plates are complete — loose plates are sometimes removed and sold separately.
Value it
Scan the book (cover, spine and copyright page) with AntiqueIQ for an identification and estimated value range, then compare sold prices for the same edition and condition. Related: antique maps value.
Frequently asked questions
How do I know if my book is a first edition?
Check the copyright page for edition statements and number lines, then compare with publisher conventions.
Are old Bibles worth money?
Most are worth modest sums; very early or rare printings can be valuable.
Does a dust jacket matter?
For many 20th-century first editions, yes — it can be a large part of the value.
