Thanks oldbookshopnj. Trouble is, many of the books I have signed don't have comparison copies on Ebay or elsewhere. Perhaps some were rarely signed. When a book price is high or the book is scarce but on a desirable topic (I've learned a bit about this from previous Ebay auctions), I have a hard time vetting the book. I know that some brave souls here start a book at a relatively low price and let bidders go for it but I don't have nerves of steel and find that method has results that vary from week to week.
I do like the Buy it Now option when I can't find info on a scarce or even rare book. Also, if a book was meant to be sold only in certain countries (and the book title page indicates such) does that possibly add to the value? I had one book, early edition, Jane's airplane book (which I knew was desirable) and the fact that it had Japanese stamped info on the front section as well as vintage photos (loose and in the book) were reasons that one bidder bid higher on that one (as he told me).
