Looking for an opinion Re: Earthrise Astrotrain

So this may or may not have been dumb, but I do want to get some opinions. I never liked the battle damage on Earthrise Astrotrain. I read one day that you could get rid of it with an eraser. I tried it out and lo and behold, the damage was disappearing without affecting the underlying plastic. I didn’t finish erasing it just because life happens, but I fully intended to finish.

A few months later I made the decision to start selling some of my Hasbro CHUGs and start collecting third-party legend figures (I now have 10 or so). I’ve basically been selling off what I can replace with legend. For example, sold TR Octane for MFT Poisonous Fog.

Now I’m eyeing Iron Sky - MFT’s Astrotrain. I hadn’t been thinking of selling ER Astrotrain when I started erasing the battle damage, but here we are.

Any thought on how much value would drop because of the figure missing the battle damage? Or perhaps, is the battle damage ugly enough that having it gone might bump up the value a bit?
