hi there. the forum you originally posted this on was on smashingpumpkins.com. i remember your thread there. this forum has disappeared now, and been replaced by http://www.smashingpumpkinsnexus.com. (i’m not sure if that messageboard is coming back or not.) so that explains why you can’t find it anymore.
good luck with this tape. the insert looks a bit dirty, but this is rare and old, so i agree with the other estimate: it’ll make a good sum of money. it’s hard to say how much exactly. could be $100, could be a lot more.
there are about 400 copies, according to http://www.spfc.org/songs-releases/disc … cog_id=119.
