One of my absolute favorite Prop sellers is VIP Fan Auctions. Recently VIP Fan Auctions made the announcement that they will be selling items from the short lived Fox TV show Terra Nova! Just a guess at what could be sold would be Wardrobe, Set pieces and various screen used Props.
VIP Fan Auctions primarily sells on Ebay, a Seller I have personally bought items from. VIP has a high customer rating and all items are authentic and usually have a COA from the studio. Below is a link to the Ebay store , no date is indicated on the site so you will just have to watch the site for updates.
