HonestBookAI FAQ

How accurate are the valuations?

HonestBookAI produces estimate ranges based on edition identification, condition assessment, and comparable realized sales, not asking prices. Accuracy depends on available market data for your specific book. High-confidence valuations are supported by multiple recent comparable sales. When comps are limited or the edition is uncertain, we say so and widen the range accordingly. We do not invent certainty.

What data is used?

Valuations draw on realized sales data from major auction houses and established rare book dealers, prices books actually sold for. Market data is weighted by recency and similarity to your specific copy. For edition identification, bibliographic reference data and publisher-specific guides are used alongside photo analysis.

What is a valuation range, and how should I interpret it?

A range reflects real price variability in the market for comparable copies. The low end represents a quick or modest sale; the high end represents an optimally presented copy to a motivated buyer. Most transactions fall somewhere in the middle. A wider range typically means thinner market data or more condition/edition uncertainty.

When should I seek a specialist instead?

For books above approximately $1,000-$2,000 in estimated value, for unusual provenance situations (notable signatures, famous ownership history), or for very early books (pre-1800), a certified specialist appraiser or a member dealer of the ABAA is appropriate. HonestBookAI is designed to supplement, not replace, specialist expertise for high-stakes decisions.

Is this a legal appraisal?

No. HonestBookAI provides an informed valuation estimate, not a certified appraisal. It is not suitable as standalone documentation for insurance claims, estate tax filings, or legal proceedings. A certified appraisal from a qualified professional is required for those uses.

What if I disagree with the result?

Every valuation includes the reasoning behind it: edition signals, condition factors, and comparable sales considered. If you believe something was missed or misidentified, use the Report a problem link in the report to flag it. Our team reviews flagged reports.

How long does a valuation take?

Most valuations complete within 2-5 minutes. Occasionally, complex editions or books with limited market data take slightly longer.

What photos should I upload?

At minimum: front cover, title page, and copyright page. For hardcovers, add front and back dust jacket panels and the front/back flaps. For potentially valuable copies, include spine, boards, and any significant condition issues. Better photos produce more accurate valuations.
