If you are looking to sell off of ebay, you can post at Scalehobby by clicking on the link in my sig. The book values are as follows:Shuttle Tyridium $30-50, AT-AT $30-50, Speeder Bike $12-17, You didn't specify issue or conditions so I just gave you the earliest released kits prices for mint sealed kits, which brings me to the Falcon. The first issue of the Millennium Falcon is $100+. remember these are not fixed retail prices but they will give you an idea what a collector will pay for them. I hope this helps and I would be curious to know what you will take for the AT-AT & Shuttle.
