Definately has value! Can't tell you how much as i'm no pricing expert but not only is it a now rare (and high quality!) Muppet item but there's also the whole game collector market as well. Lots of people would love to have it within and outside the Muppet community.
Which do you have? The first one where you get a pair of Muppet characters to the appropriate set or the second one where you auditioned for Muppet judges? Both games have very cool covers as well as boards with lots of rare obscure characters represented.
