I have 2 pairs of 12 generator points regen and all colors regen what is the worth or them If I was to sell them?

I am guessing you mean Nytekries, since the revamp just happened they are only really worth 15-20k as most people have them and/or regened them

Another issue causing the low price for regennable nytes is that the traits that can be regenned are severely limited, and unless you list exactly what traits are available to be regenned, the potential purchaser won't know what they're actually buying (as opposed to previous regens where the owner had much freer rein to choose from any trait at all, or any trait within a certain trait slot).
