4,5,6 definately, 3 and 7 possibly. [all hardcover UK]
i think my versions of PS/CoS are like 40th/30th editions, [paperback UK] worth squat unfortunately, as i think 1st edition of PS is probably worth thousands, i mean 1st editions of the later books were printed in vast numbers, so probably aren't worth much more than what was paid for them.
