Incunabula
Books printed before 1501, during the earliest years of the printing press, are known as incunabula and are extremely valuable due to their historical significance and rarity. Most of these books are now in institutional collections, but when they do appear on the market, they frequently sell for six or seven figures.

Where to Sell Valuable Old Books
Rare Book Dealers
Specialized rare book dealers have the expertise to properly value and market your books to the right collectors. While they will pay less than the retail price (typically 40-60% of eventual selling price), they offer convenience and expertise. To find reputable dealers:
- Antiquarian Booksellers’ Association of America (ABAA) lists verified professional rare book dealers
- International League of Antiquarian Booksellers (ILAB) provides connections to dealers worldwide
Auction Houses
For particularly rare or valuable books (generally worth $1,000+), auction houses can be an excellent option. Major auction houses with dedicated book departments include:
- Christie’s and Sotheby’s for very high-value items
- Heritage Auctions, Bonhams, and Swann Auction Galleries for a wider range of collectible books
- Regional auction houses for more moderately priced rare books
Auction houses typically charge a seller’s commission of 10-15% but can often achieve higher prices through competitive bidding.
Online Marketplaces
For books of moderate value ($50-$1,000), online marketplaces allow you to sell directly to collectors:
- AbeBooks: Partner site for professional booksellers
- eBay: Large audience, particularly good for illustrated books that show well in photos
- Biblio: Focuses on rare and collectible books
- Amazon: Better for more common books in very good condition
These platforms charge listing fees or commissions but give you direct access to buyers worldwide.
Book Fairs
Annual book fairs in major cities attract serious collectors and can be good venues for selling valuable books. The ABAA and similar organizations host regular book fairs in cities like New York, Los Angeles, Boston, and San Francisco.
Preserving Your Valuable Books
Storage Environment
The ideal storage environment for books includes:
Optimal Book Storage Conditions
Aim to maintain these conditions for valuable books
Avoid storing books in attics, basements, or garages where temperature and humidity fluctuate dramatically. Keep books away from exterior walls to prevent condensation damage.
Handling Practices
Proper handling helps prevent unnecessary wear:
- Wash hands before handling rare books
- Support the book’s spine when opening
- Never force a book to open flat
- Use acid-free bookmarks rather than folding pages
- Remove dust jackets when reading regularly handled books
Protective Enclosures
For particularly valuable books, consider protective enclosures:
- Archival boxes: Custom-fitted clamshell boxes made of acid-free materials
- Mylar dust jacket protectors: Clear, chemically stable covers that protect dust jackets
- Book shoes: Open-ended sleeves that provide support and protection
Professional Conservation
For books with existing damage, professional conservation might be warranted. Book conservators can repair bindings, clean pages, deacidify paper, and address other issues. The American Institute for Conservation (www.culturalheritage.org) maintains a directory of qualified conservators.
Special Considerations for Different Types of Old Books
Children’s Books
Collectible children’s books have unique considerations:
- Condition is especially important as children’s books were often heavily used
- First editions of classics like “Alice’s Adventures in Wonderland,” “Winnie-the-Pooh,” and “The Tale of Peter Rabbit” can be extremely valuable
- Illustrations by famous artists significantly impact value
- Original dust jackets can account for 80% or more of a children’s book’s value
Comic Books and Graphic Novels
Comic book valuation has specialized factors:
- Grading scale: Comic books use a standardized 10-point grading scale from Poor (0.5) to Gem Mint (10.0)
- Key issues: First appearances of major characters or significant storylines command premiums
- Authentication: Professional grading services like CGC provide slabbed, authenticated comics
Antiquarian Religious Texts
Religious texts have been printed for centuries and have specific value considerations:
- Early Bibles, particularly pre-1700 examples, can be quite valuable
- Complete texts are worth significantly more than incomplete copies
- Original binding, particularly fine leather work, adds substantial value
- Illuminated or illustrated religious texts command premium prices
Signed and Association Copies
Books signed by authors or previously owned by notable individuals (association copies) require special evaluation:
- Authenticity is paramount - provenance documentation adds significant value
- Inscriptions to notable individuals are generally more valuable than simple signatures
- The significance of the association matters (e.g., a book given by an author to their editor or muse)
The Future of Old Book Values
Rising Categories
Several book categories have seen consistent value growth in recent years:
- Modern first editions: Particularly those from the mid-20th century by authors like Ian Fleming, J.R.R. Tolkien, and George Orwell
- Counterculture and protest literature: Works from social movements of the 1960s and 70s
- Children’s picture books: Particularly first editions of enduring classics
- Science fiction and fantasy: Especially foundational works of these genres
Impact of Digital Collections
As more books become digitized and accessible online, physical copies of common texts may decrease in value. However, this has seemingly increased the premium placed on books as physical objects of beauty and craftsmanship, with fine bindings, illustrations, and limited editions seeing strong demand.
Collecting Demographics
The collector base is evolving. While traditional rare book collecting was dominated by older, wealthy individuals, younger collectors are entering the market with different interests, often focusing on:
- Books related to social justice movements
- Works by women and people of color who were historically underrepresented
- Books with cultural significance to specific communities
- Illustrated books and those with striking visual appeal
This demographic shift is gradually reshaping which books are considered most collectible and valuable.
Common Questions About Old Book Values
Frequently Asked Questions
How can I find out what my old books are worth?
The most practical approach is to research similar copies online through sites like AbeBooks, Biblio, or Vialibri. Look for books in similar condition with the same edition points, and check both current listings and recently sold copies. For potentially valuable books (over $1,000), consider a professional appraisal from a member of an organization like the Antiquarian Booksellers’ Association of America.
Does the age of a book automatically make it valuable?
No, age alone does not determine a book’s value. Many old books have minimal financial value despite their age. Value is primarily determined by rarity, condition, demand, and significance. A first edition of a significant work published in the last century can be worth far more than a common religious text from the 1700s.
How can I tell if I have a first edition of a book?
First edition identification varies by publisher and era. Look for a statement like “First Edition,” “First Printing,” or “First Published” on the copyright page. A number line that includes “1” (e.g., 10 9 8 7 6 5 4 3 2 1) is also common in modern books. Some publishers use specific codes or identifiers. For valuable works, consider consulting specialized bibliography references for that author or publisher.
At what age is a book considered an antique?
In the book trade, “antique” generally refers to books 100 years old or older. Books between 50-100 years old are typically described as “vintage.” However, these terms aren’t rigidly defined in the book world, and age classifications can vary among dealers and collectors.
How important is having the original dust jacket?
For books published after 1920, when decorative dust jackets became common, the original dust jacket is extremely important. A dust jacket can account for 80% or more of a book’s total value, particularly for modern first editions. Books from the mid-20th century in fine condition but lacking dust jackets may be worth only 20-30% of what comparable copies with jackets would command.
Should I repair or restore my old book before selling it?
Generally, no. Amateur repairs almost always reduce a book’s value. Even professional restoration can impact value for certain collectors who prefer unrestored copies. Minor cleaning (like gentle dust removal) is fine, but leave significant repairs or restoration to the new owner or a professional conservator. If a book is very valuable, consult with a rare book expert before attempting any conservation.
Are library books ever valuable?
Books with library markings (stamps, pockets, spine labels) are generally considered less desirable by collectors and typically sell for 30-70% less than unmarked copies. However, exceptions exist for extremely rare titles where ex-library copies might be among the few surviving examples, or for books from historic libraries with significant provenance.
How can I identify a valuable book collection I've inherited?
Start by looking for first editions of notable authors, books with author signatures or inscriptions, fine leather bindings, limited editions, and illustrated works by recognized artists. Create an inventory of titles, authors, publication dates, and notable features. Research highlights online or consult with a rare book dealer who can review the collection. For large collections, consider hiring an appraiser who specializes in books.
Additional Resources for Book Valuation
