Of my following of Mego's I have seen realistic prices of Carded ones, that only have 4 or 5 in collectors hands, go for upwards of $10k. The Aquamans Shark Attack goes for close to that Sealed in a nice box. Since this is made by Mego but not of the Action figure variety, It might not hit that number.If I am correct I don't think a Plastic man MIB has gone for more than 5k. I think to a hulk collector it might be worth more. My Estimation would be around 5k, but as Gator said. There hasn't been one up in for ever and the only white box, I have seen. Either way it is a very nice piece. You never know.
