I have the original NM and FWC cloaks for my hunter, I have Praetorian Foil, all the VoG hunter armour (not really rare but I'll probably keep them for nostalgic purposes) I think I have one of the original emblems (sign of the founders or something like that) and I think that's about it. EDIT: I also have the Rope To Heaven ship which you get by finding blueprints, dunno how rare that is now though.
