"I Found This Old Book in My Attic": What to Do First

You have found an old book — perhaps in an attic, a basement, an inherited box, or a grandparent’s house. It looks old. It might be valuable. Your first instinct is to clean it up, look up prices, and possibly sell it. Resist all three impulses until you have completed the steps below. How you handle the next thirty minutes can determine whether the book is worth $5 or $5,000.

Step 1: Do Nothing to the Book

This is the most important step and the one most people skip. Do not:

Clean it. Do not wipe the cover with a damp cloth. Do not brush the pages. Do not use household cleaning products. Do not remove dust or dirt from the edges. Improper cleaning can damage bindings, remove original patina, and create stains that were not there before.

Repair it. Do not tape torn pages. Do not glue a loose spine. Do not press down lifted corners of the dust jacket. Every amateur repair reduces the book’s value. Professional conservators work with reversible materials and specialised techniques — household tape, white glue, and rubber cement are destructive.

Write in it. Do not write your name, the date, a price, or any other information in the book. Even a pencil inscription reduces value.

Remove anything. If the book contains loose items — letters, photographs, bookmarks, newspaper clippings, pressed flowers — leave them in place. These items may be part of the book’s provenance and history, and they may add significant value.

Force it open. If the book is stuck shut, has pages adhered together, or has a binding that resists opening, do not force it. You may cause damage that cannot be undone.

Step 2: Record Basic Information

Without handling the book more than necessary, note the following:

Title and author. Read them from the spine or cover. If the spine is too damaged to read, open the book gently to the title page.

Publisher and date. Open to the copyright page (usually the back of the title page) and note the publisher’s name and the publication date. Photograph this page with your phone.

Condition of the dust jacket. If the book has a paper dust jacket (the paper wrapper around a hardcover book), note whether it is present, intact, or damaged. The dust jacket is often the most valuable component of a twentieth-century book.

Overall condition. Note any obvious damage: torn pages, missing covers, water stains, mold, insect damage, missing pages.

Any signatures or inscriptions. Check the title page, the half-title page (the page before the title page), and the free front endpaper (the first blank page when you open the cover) for handwritten signatures, inscriptions, or dedications.

Step 3: Determine What You Have

Now — and only now — use the internet to research the book.

Search for the exact title, author, and publisher on AbeBooks.com and look at the range of prices for different editions and conditions. Pay attention to whether the copies listed are first editions, later printings, book club editions, or reprints. The price range can vary enormously depending on the edition.

Check the copyright page. Does the page indicate a first edition or first printing? Look for a number line (the lowest number indicates the printing), a “First Edition” statement, or the absence of later printing statements. If you are unsure, photograph the copyright page and post it to a book-collecting forum or subreddit for identification help.

Check for book club indicators. If the dust jacket has no price on the front flap, the book may be a book club edition (virtually worthless to collectors). If there is a small blind stamp (a pressed circle, square, or dot) on the back cover, it is almost certainly a book club edition.

Step 4: Assess Realistic Value

Most old books are not valuable. This is a statistical fact, not a discouragement. The vast majority of books printed in the past 200 years — including most hardcovers, most “old-looking” books, most Bibles, most encyclopedias, and most book club editions — have minimal market value.

Books that are potentially valuable include: first printings of significant literary works, signed or inscribed copies by notable authors, books with notable provenance, books from limited or fine press editions, and books in exceptional condition with original dust jackets.

If your research suggests the book might be valuable (comparable copies selling for more than $200 on AbeBooks or at auction), proceed to Step 5.

Step 5: Get Professional Assessment

For potentially valuable books, consult a professional before attempting to sell. Options include:

An ABAA or ILAB dealer. Members of the Antiquarian Booksellers’ Association of America or the International League of Antiquarian Booksellers can evaluate your book and give you a realistic assessment of its market value. Many will do this by email with photographs.

An auction house specialist. Major auction houses (Christie’s, Sotheby’s, Bonhams, Heritage, Swann) have book specialists who will evaluate potential consignments.

A professional appraiser. If you need a formal valuation for insurance or estate purposes, hire a qualified appraiser. Expect to pay $100–$300 for a formal written appraisal.

Do not accept the first offer you receive. Get at least two independent opinions on valuable books.

What Most Attic Books Are Actually Worth

The honest truth: the vast majority of old books found in attics, basements, and inherited collections are worth between $0 and $20. Old Bibles (even very old ones) are usually worth less than $100 unless they are pre-1700 or have exceptional features. Encyclopedias from any era are essentially worthless. Book club editions have no collectible value. Reader’s Digest Condensed Books are worth nothing.

But outliers exist. Every year, genuine treasures are discovered in attics and estate boxes — books worth thousands or tens of thousands of dollars that their owners had no idea were valuable. The key is following the steps above: do not damage the book, research it carefully, and get professional advice before making any decisions.

Frequently Asked Questions

Should I clean old books I find in the attic? Do not clean them beyond gently removing surface dust with a soft cloth. Do not use water, cleaning solutions, erasers, or any chemical on the pages, binding, or dust jacket. Improper cleaning causes more damage than dirt.

How do I store old books while I research them? Place them upright on a clean shelf in a cool, dry room away from direct sunlight. If they smell musty, do not seal them in plastic — allow air circulation. If you see signs of active mold (fuzzy growth), isolate the affected books in a separate area.

Is it worth getting every old book appraised? No. Start with a quick online search (AbeBooks, Rare Book Hub) to see if comparable copies are listed for significant prices. Only invest in a professional appraisal for books that show initial signs of value — first editions of important works, signed copies, or books with unusual features.
