Best place to sell my soundtrack collection in UK

I have various soundtracks that I wish to sell, all original and in great condition, some relatively rare and some signed by composer, I want to get the best price possible but ideally wanted those who appreciate soundtracks to get visibility on these so are there specialist places I can sell these or is eBay the only real option? Thanks.
