The most I've ever made on a book was $100 on an early edition Walt Whitman that I chanced upon in a very small thrift store. The buyer left feedback and said the book was better than I described. I think I was so afraid of not representing it accurately that I probably overstated its flaws. I'd rather do that than the other way around.
It's fascinating to read the descriptions written by experienced collectible book sellers. And it is amazing the books that are sold on ebay. Very rare books that go for thousands of dollars. So the other day I decided to spend a little time perusing the category and quickly noticed a BOLO which surprised me, A Game of Thrones (my brain always reads this as A Game of Thorns). I've heard of the tv show Game of Thrones and I know it is really popular but that's as much as i know. I can't even tell you what it is about. Well it's based on a novel of the same name written in 1996. A first edition goes for $400+ dollars. You can bet I'll be looking for that from now on. It's got a silver dust jacket that should be easy to spy on a shelf of books and then a look inside will tell you if it is a first edition.
Here is a pic
and the sold listings. If it's signed you've really hit gold but either way a definite BOLO. Do any of you watch the show? Read the book? Maybe you have a first edition sitting on your own shelf?!
