i am currently looking at purchasing a copy of this self same book and the most expensive I've seen was priced at £340.00 and I have also seen them at £3.00.
if i were you I'd have a look on Abe books as they have numerous copies and possibly you could work out what yours is worth by reading a few descriptions of the ones advertised on there. as I'm sure you'll be aware it all depends on edition, condition and what someone is prepared to part with?
hope this helps
