As the subject says...

I have recently acquired a large collection of records, and there are hundreds if not thousands of trance tunes. This isn't really my speciality (save for a few months in 99 or so) so I'm looking for some advice on where to sell them. It was a pro DJ's collection, and as such there are lots of unreleased, tests, bootlegs and promos some of which are on Discogs for up to £100, but do they actually sell at those prices? Is ebay the place? Or forums like this?

Any help would be much appreciated.

try craiglist discogs ebay or the selling section on here.
