Does anyone know what this doll is worth: Halo 3 Blue Spartan?

I don't think it was produced for mass retailing. I won it 11/07, in a sweepstakes from Mt Dew & 7-11. I saw somebody offering $400 for it the first week after they were shipped to the winners. I never checked into it again, until now.
