Question about WOT books

[Tothelight]

I recently started cataloging my library and came across a couple WOT books. One of them is a 1990 version of Eye of the World and the other two are both hardback versions of the Path of Daggers.

 

I would appreciate some guidance from some of the possible collectors here on the value of the books.

 

Thanks!

I am not really a collector. From my understanding, first editions sell for more than other editions; and signed first editions sell more than other first editions.
