Hello everybody,
I am looking around for The Lord of The Rings and The Hobbit editions published by Unwyn Hyman.

I was wondering how rare are those since I can't find publication count on tolkienbooks for both, and how valuable could they be (I'm not sure and I wouldn't want to spend too much).

These are the links to the books:

LOTR: http://tolkienbooks.net/php/details2.php?id=1205

Many thanks, best,
