I sold my adult spider that was 50% Het albino as with a normal spider price( for a adult, and i still think i was way under their market value). As said before, i did not do the breeding or have paper work so i was not going to jack up the price for something i was not sure about. The person i got her from said her dad was a het albino, and paper work is only as good as the breeder when it comes to poss hets so i did not worry about getting any at the show . I let the buyer know and i just considered it as a bonus if she ever trys to prove her out.
