I sell things on Ebay and was getting ready to post a bunch of stuff in my store and up for auction. I have a book I got my daughter a few years ago, but she never read it. As usual I always check Amazon.com for book info and also to get an idea about pricing. This book: On Top of Concord Hill (Little House) by Maria D. Wilkes from 2000 is priced $55 USED. One seller has it for $220! What in the world is that? The copy I have is in great shape. Just don't have the dust jacket. I found no copies of it for sell on Ebay. My book has the same ISBN's as these other books listed for this price. Do I have a rare book? If so what should I start it off at on Ebay?
