Dan BrettaI have two books that I would consider rare, but their value is probably not a whole lot because they are probably only wanted by a select few collectors. I got them off of ebay and very little competition.
This first one I believe to be extremely rare and I have only seen just this one copy....The Yale library of rare books has this book listed in their inventory, but they have it dated as 1903...this one is dated 1900. 
This one is hard to find, but I have seen I think 5 original copies of the 4th edition...I have never seen any other edition besides this one. This was reprinted in 1991 or 1992 and you can find copies on ebay or Amazon on occasion.
Barry, I beat you by about half an hour to the first post.
