After witnessing the price people pay for Stadium Events NES carts one can never underestimate the stupidity around 1980s video game cart collectors. I could turn your situation/story around and ask about a rare NES exercise cart and it would be as interesting to me as crushed plastic and far less than anything to do with E.T.
Whether they find it or not I'm sure the video will get a lot of views so I guess if they put ads on it...
