For me - priceless.
There isn't any way I could put a dollar value on my trains - the fun of the hunt for an elusive piece to add to the collection, the joy of building and photographing dioramas, the thrill of having some of those pictures make the front cover of TCQ and the picture section in CTT, the carpet central constructs and what they have meant to me and to my many visitors over the years, the sense of satisfaction after completing a build either from a kit or scratch, ...and on and on.
For the final hammer at the auction - whatever they sell for.
