Determining a rare book’s fair value

by The bookworm on April 28, 2011 · Market Analysis, Rare Book Education

One of the hardest tasks for a seller or owner of an antiquarian book collection, is evaluating or determining a book’s fair value. Whether preparing to sell or appraise your books for any reason, the unique attributes inherent in the world of rare books, deems the task “approximate”.

Finding out a book’s current value, in theoretical terms, comes down to what a buyer is willing to pay for it. How valuable a book is, it usually depends on a number of factors including scarcity, condition, special features such as autographs and inscriptions by authors, and a factor I refer to as investment appeal. A buyer of an antique or scarce book is usually a collector who is potentially looking to add value to her/his collection by acquiring a certain grouping of complementary hard to find books. A book dealer is investing in a category of books that she/he specializes in, with a primary intention to sell for profit. A measure of a book’s investment appeal is probably the most difficult factor to quantify.

The fact that no two books are alike complicates things a bit. The same title by the same author having the same publisher and edition, printing, state etc., does not necessarily have the same value. Other criteria, such as unique features (signed, inscribed, autographed), the condition of the book, the timing of the evaluation or the purpose of the appraisal can contribute to the evaluation.  A case-by-case determination can vary considerably resulting in significant fluctuations. Take as an example a rare book by the name, Codex Seraphinianus, first edition limited to 4000 copies printed by FMR (Franco Maria Ricci of Italy) in 1981. The book sold on Abebooks in March of 2010 for 6000 US Dollars. A year later the same book sold for 955 Euro, on Ebay. Same book, similar condition, different channel, different time, different seller location.

Combining historical data from past pricing sale activity, while adjusting upward or downward to accommodate pertinent current criteria, is in theory the ideal process. A number of different agencies have been tracking past sale information:

1)      American Book Prices Current (ABPC) reports on prices brought for specific items in a specific condition at major auction houses in the United States, the United Kingdom, and Europe.

2)      Bookman’s Price Index (BPI).  Some 100-200 antiquarian booksellers in United States, Canada, and the United Kingdom report their prices to BPI.

Once the historical pricing is determined and all current unique criteria factored in, a final step is channel determination. Channel is important since a book placed in an auction is exposed to different market conditions than a book placed for sale on a shelf in a local bookstore. If the purpose of the evaluation is to price a book for sale, then expected returns are dependent on the sale channel. Auctions are usually used to quickly liquidate a tangible asset, within current market conditions and within a relatively short time frame compared to say listing the asset for sale on Amazon.

As with any tangible asset, time is a prime contributor to value fluctuations. A long-term approach to maintaining pricing up-to-date is extremely important. How often to re-evaluate and adjust a book’s value, is a topic for a future date.

I have a set of 10 Rorschach test cards. The box does not look like the others that I see online. There is no copyright or publishers date. Others that I find online have more printed information on the cover box. This has an orange label adhered to the box that reads “Dr. Hermann Rorschach PSYCHODIAGNOSTIK Tafeln”. Under that label is another that reads “ imported by Grune & Stratton, INC. medical publishers New York “. These are actual lables and not just printed on the box. The top right corner has been stamped “ Printed in Switzerland “. The test cards have no date, the back of each card has a Roman numeral on the top left corner and the bottom left reads “Arb. z. angew. Psychiatrie, Bd.II. Rorschach: Psychodiagnostik IV. Auflage. Verlage Hans Huber, Bern.

I have a book I would like to have information on. The title is Lector Infantil by Gregorio Torres Quintero. It was published in 1906. It is in Spanish and seems to have been done when he was a teacher at a school. The book also has a university of Oregon Sticker from 1907.

Gregorio Torres Quintero (Las Palmas, Colima, May 25, 1866 – Mexico City, January 28, 1934) was a Mexican teacher, pedagogue, storyteller, and innovator in teaching systems. He founded the Escuela Modelo for primary, normal and tutor education, in 1892. He was director of the Porfirio Díaz School and for a short period he was head and director of Public Instruction.
El lector infantil mexicano was his eighth book

I have an old copy of The Prince of the House of David. It is not a reprint. Hard cover all complete, good condition. I would guess it has been sitting on a bookshelf for most of the past hundred years.

Hi there, wondering if you can help. I have a copy of China’s Millions 1891 and a copy of China’s Millions 1892. They are not reprints. One is green, the other red, both with lot’s of gold leaf on the cover. They are both in excellent condition with only small dings in the corners. Inside, the books look like they’ve never been opened. They both had a dedication written
inside – Presented to the Wesleyan S.S. Library by J.V. Breaden. S.S. perhaps meaning Sunday School as they came from a church sale in Tasmania. Really hoping you can help as I can only find fairly recent reprints online. Look forward to hearing from you. Regards Mary T.

I have a Dell 1st edition (paperback) of Vonnegut’s Slaughter-House Five, published in October of 1971. On EBAY, I see it going for $85 and again for $19.95. That’s a big difference. Both items look identical to mine, so now I’m confused as to what mine is actually worth. Can anybody help?

I have a copy of The Art, Science, and Philosophy of Chiropractic, by D D Palmer. It is the green book, that I believe is the 1966 reprint of the 1910 version. It is in great condition. I already have several people interested in buying it, sight unseen, but I do do know what the value of the book is. I understand that is is listed in several places as a scarce book to find. Should I just list it on bay and let the action begin? At what price? Or should I sell to one of these gentlemen?

Any suggestions you can give me will be appreciated.

Thank you,

Melody MIller
