We are talking Apples and Oranges here. Any REAL vintage book would never be listed on Amazon. Perhaps on eBay. The only way to get an idea of value is to ask an antiquarian book seller or an auction house specializing in these things. Condition has to be REALLY GOOD with the dust-jacket intact, no tears, writing, rips, damaged spines and there must be DEMAND for the book. I've seen none in this thread. Collectors scour forums like these looking to buy - no interest so far so I doubt that there is any "big" value in any of these books.
