Hey, cool find. Some modern posters hold a little bit of value but the difficulty comes in selling them and making any money. Off the top of my head some of the best modern ones are jurassic park and nightmare before christmas and if you have an lenticular posters(3d). there are movie poster auction sites like emovieposter.com and ha.com but you wouldn't make much through them. emovieposter is a great site but to make it worth the trouble they would take probably 70% of the sale price for items selling under 15 bucks. Heritage Auctions probably wouldn't even accept most of them. I've never used them but you could look into movieposterbid.com. selling them in lots on ebay might be your best bet either way. If you have a complete list I might be able to save you some time by buying some if you have some I might be looking for. email me if you get a list together and we can worry about pictures later.
