Hi there, New to these forums, but a friend suggested I post here for feedback, apparently especially from @joeypost, please and thank you. When I was a kid I purchased two copes of GI Joe #1. One I read and sold years later for 10$. The other I kept in the original hanger bag I purchased it in, and locked it away for decades. I recently thought to have it graded to protect it further and hoped for a good grade given it was never opened. However, I have gotten conflicting answers. Some think its a 7 some think it at best wouldnt get above a 9.4. Others have suggested not to remove it from the original hanger bag as they have only seen 3-4 like this in 40 years of collecting and as such is unique and very rare. I did contact CGC and was informed they would have to remove the bag to grade, understandable because of the whiteness of pages and folds etc. Other comments and suggestions included that the bag might be harming the book because of it not being acid free. Since this seems, and I have been told, this is the cream of the cream of collectors and experts on grading and submissions ... I am asking for your help and suggestions or guidance. Mainly, do you think I should have this submitted for grading? Or should I keep this in the original hanger bag as it is "rare and unique"? Will the bag destroy the comic? (its been in it for 40 years and doesnt seem to have done damage but thats also why I am asking here. If you use technical terms for grading, please explain as I am new to comic grading. I am used to sports/tcg grading. Originally, I was hoping for a "authentic" or such grade or one like they use on packs/boxes in the tcg/sports side. Your feedback is greatly appreciated. If you need further pictures, please just specify and I would be happy to provide them. Any creases you see are just a reflection of light on the bag itself. It was stored in a bag, between two pieces of cardboard, flat and inside a cardboard comic box for the last 30-40years. Thanks in advance
