Well let's just say the super would be an all black snake. The fact he is so dark doesn't point inc co-dom to me. Because I don't see that as the half-way point to a super form. If that makes sense? So we are more than likely looking recessive. I'm already cautious because I'm curious who imported this guy.
As for pricing if genetic, the public likes bright, high contrast animals in general, but some dark mutations have been very popular, but they show a tremendous array of dynamic combo ability that have more contrast and different tones than this guy. I don't see it being priced super-high unless it unlocked something cool, but I just don't see it ATM. I do think its original, and id like one in my collection if it was proven, but I probably wouldn't spend more than 5k unless it showed combo ability. Hope that helps.
