Has anybody gotten an autographed comic and you’re unsure about it?

Please, no judgement. I’m new to this. Long story short, I placed a bid for a Stan Lee autographed Spider-Man comic. And I placed the highest bid. The comic account has over 5k 5 star reviews, so I thought, “this is legit.” I was so excited, I didn’t even care how it looked… until I reached out to a professional comic club. The guy said it could be real or not real, because the “Stan” doesn’t look so confident, but the “lee” is definitely it… I’m definitely submitting this to JSA. It’s GAA approved, but GAA doesn’t seem so legit…
