So there's no way of knowing if the signature will negatively impact the grade?
I'm very new to collecting comics, if someone wouldn't mind giving their opinion on my situation. I have a comic that is signed with a COA. I know it can't be verified by CGC, however do you think there is still value in having it graded and slabbed? Would you prefer that CGC graded/slabbed it over another company like CBCS/PGX (hopefully not taboo to ask here) that may certify signatures, or would you rather it just be raw?
