How to Get a Rare Book Appraised — Finding an Appraiser and What to Expect

A professional book appraisal provides an expert’s written opinion of a book’s market value. Appraisals are needed for insurance coverage, estate settlement, charitable donation tax deductions, equitable distribution in divorce, and general knowledge of your collection’s worth. The key is finding a qualified appraiser and understanding what the appraisal process entails.

When You Need a Professional Appraisal

Insurance

Your insurance company may require an appraisal to establish the value of your collection for coverage purposes. The appraisal should state “insurance replacement value” — the cost of replacing each item with a comparable example at current retail prices.

Estate Settlement

When a book collection is part of an estate, an appraisal establishes fair market value for estate tax purposes and for equitable distribution among heirs. If the estate is subject to federal estate tax, the IRS may require a qualified appraisal.

Charitable Donation

If you donate books valued at $5,000 or more to a qualifying institution, the IRS requires a qualified appraisal. The appraisal must meet specific IRS requirements regarding the appraiser’s qualifications and the appraisal document’s content.

Sale Preparation

Before selling a valuable book or collection, an appraisal helps you understand its market value and choose the appropriate selling venue (dealer, auction, private sale).

General Knowledge

Simply knowing what your collection is worth — for peace of mind, for estate planning, or for collecting strategy — is a legitimate reason to seek an appraisal.

Finding a Qualified Appraiser

Professional Organisations

Antiquarian Booksellers’ Association of America (ABAA). ABAA members are established rare book dealers who adhere to a code of ethics. Many ABAA members offer appraisal services. The ABAA website (abaa.org) has a searchable directory.

American Society of Appraisers (ASA). The ASA accredits appraisers in various specialties, including “personal property — books and manuscripts.” ASA-accredited appraisers have passed examinations and demonstrated expertise.

International Society of Appraisers (ISA). Another professional body that certifies appraisers in personal property categories.

Qualifications to Look For

• Demonstrated expertise in the type of books you need appraised (a dealer specialising in Americana may not be the right appraiser for a collection of Victorian illustrated books)
• Professional membership in ABAA, ASA, ISA, or equivalent
• No conflict of interest — the appraiser should not be buying the books they are appraising
• Willingness to provide references from previous appraisal clients
• Understanding of the specific appraisal purpose (insurance, estate, donation — each requires a different valuation standard)

Who NOT to Use

• The person or dealer who wants to buy your books. An appraiser who will profit from a low valuation has an obvious conflict of interest.
• Online “appraisal” services that offer valuations based on photographs without physical examination. These are estimates at best and unreliable at worst.
• Generalist antiques appraisers who do not specialise in books. Books require specific expertise that most generalist appraisers lack.

The Appraisal Process

Step 1: Initial Consultation

Contact the appraiser and describe your collection: approximate number of books, general subject areas, any titles you believe may be significant, and the purpose of the appraisal. The appraiser will tell you whether they are qualified for your material and provide an estimate of their fee.

Step 2: Physical Examination

The appraiser examines the books in person. For each significant item, they note:

• Title, author, publisher, date
• Edition and printing identification
• Physical condition (binding, dust jacket, pages, completeness)
• Any signatures, inscriptions, bookplates, or other notable features
• Provenance information

For large collections, the appraiser may examine every item or may sample representative items and extrapolate for the remainder, depending on the purpose and scope of the appraisal.

Step 3: Research and Valuation

The appraiser researches current market values using:

• Recent auction results (Rare Book Hub, auction house archives)
• Dealer offering prices (AbeBooks, dealer catalogues)
• Their own market expertise and experience
• Standard bibliographic references

Step 4: Written Appraisal Report

The appraiser produces a written report that includes:

• The purpose and intended use of the appraisal
• The valuation standard applied (fair market value, insurance replacement value, etc.)
• A description of each appraised item
• The appraised value of each item and the total collection value
• The methodology used
• The appraiser’s qualifications and signature
• The date of the appraisal

For IRS purposes (estate tax or charitable donation), the appraisal must meet specific format and content requirements outlined in IRS regulations.

What Appraisals Cost

Appraisal fees are typically charged as:

Hourly rate: $100–$300 per hour, depending on the appraiser’s qualifications and the complexity of the material. A collection of 50 books might take 4–8 hours to appraise (including research time), costing $400–$2,400.

Per-item fee: Some appraisers charge a flat fee per item, typically $25–$75 per book for formal written appraisals.

Flat fee for a collection: For large collections, some appraisers offer a flat fee based on the estimated scope of work.

Important: Never hire an appraiser who charges a percentage of the appraised value. This creates a conflict of interest — the higher the appraised value, the more the appraiser is paid. Percentage-based fees are prohibited by professional appraisal organisations.

Verbal Opinions vs. Formal Appraisals

Verbal opinion: An appraiser or dealer examines your book and gives you an informal verbal estimate of its value. This is appropriate for casual enquiries but is not suitable for insurance, tax, or legal purposes. Verbal opinions are typically free or inexpensive ($25–$50 per item).

Formal written appraisal: A documented, signed appraisal report meeting professional standards. Required for insurance, estate, and tax purposes. This is the appraisal product that costs $100+ per hour.

Many dealers will give you a free verbal opinion if you bring a book to their shop or to a book fair. This is a good starting point for understanding whether a formal appraisal is warranted.

After the Appraisal

• Update the appraisal every 3–5 years to reflect market changes
• Store the appraisal document securely — with your insurance company, your attorney, and in a separate location from the collection itself
• Use the appraisal to review your insurance coverage and ensure adequate protection
• Share relevant information with your heirs so they understand the collection’s value
