Also another question I have 2 dark charizards, but the coloring is clerly different on the other one. any idea why? its not fake that much I have researched.
I can't help with value, but the color difference is likely due to a difference in ink levels. (This kind of difference is especially noticeable on classic Trainer cards imo, where the grey texture may appear warmer or cooler depending on the ink level at the time of printing.)
