I have access to some very expired Ektachrome 400 EL that was frozen since date of purchase in the late 80's and early 90's. It was all dated when purchased and frozen. Is this something I should try? Also, what do you think it would be worth, $1.00/roll or less?

Among these, anything I should try out? Not fo anything really important, just goofing off or teaching others without wasting $4/roll.
