Value ?

I have just been given a collection of stranger thing displate metal posters . Yet would be nice to get a decent amount of money from them as they are all brand new and in packaging still . The funny thing is I cannot find these listed on the displate website anymore but . Although I have found 3 of them in an article from a year ago . What would you value them at considering displate charges for one large is about £80 and this is a collection . Sorry for shiny pictures there still in plastic
