Anyone?
I'd give you $10 for it.
You could probably find someone who would give you $15 for it pretty easily.
If you find a sucker you might get $20.
11x plastic hasn't increased that much in value yet because it's still fairly readily available. If you can't find a store that has some on the shelf for regular Champ plastic prices, it's fairly easy to find a sucker who doesn't know what he has and that people want it.
