Not much I'm afraid. Much less for loose items without box, instruction sheet, etc.

I sold most of my Star Wars toys a few years ago.
- AT-AT loose, complete with box for $100.
- Attack on Hoth loose, complete with box $25 I think. Perhaps a little less.
- AT-ST camo paint / mud weathering loose, complete with box $70. Perhaps a little less.
- Defence of Hoth. May as well toss it in the trash can.
