Syd Barrett fanzines, question on worth...

In an effort to raise money for recording my next classical guitar CD, I would like to sell off my Syd Barrett fanzines and am curious about the value. Perhaps the more knowledgable people here could help me. I have the following Syd Barrett fanzines
1 Opel 1,2,3,4,5,6,7,8,9(2),10,11,12
2 Making of Madcap Laughs #2/21 Ivor Trueman green front/back xeroxed/stapled
3 Syd Barrett magazine #1,2 1990? Chris Manson, #1 is newsprint
4 Syd Barrett books from Syd Barrett Magazine, #088
5 Late Night magazine 1,2,3,4 1999/2000
6 Chapter 24 #2,4 1994,1996 David Parker
7 Dust and Guitars #3 1999 Denise Vacca
8 Esoteric Popular Culture #1 Syd cover story 1996
9 Terrapin complete box set
Items 3-9 are near mint and 1 and 2 have some wear but are VG+.No missing pages or tears in any of the items.
Thanks for your help.
