It depends on the issues the most expensive are issue Vol 1 issue 1 & Vol 6 issue 3. The other issues are sometimes sold on ebay usually ranging between $4-$15.
People saying vol 1 and 6 being worth more because there is no back copies left need to realize that there are no back copies left of any volume anymore lol
There was a for sake thread for a whole collection it started at $700 and just kelp coming down. Last time saw it was around $500 but I am sure it's lower now. My whole collection to piece it all together cost me about $200-250.
I realize this is an old thread.
I have seen from time to time the magazines but not the binders not sure what volume they finished with binder wise and I'm missing 2 magazines also can someone please tell me where I would start looking as newsagency can't help! Thank you
