Featured Any Comic Book Collectors Out There?

Hi
I bought a box of 11 silver age Spider-Man comics + a handful of other comics for $1,000 a couple of days ago; the main reason being the key issues Amazing Spiderman #50 (1st Kingpin appearance) & #51 (1st Kingpin cover + 1st Joe "Robbie" Robertson appearance) - which looked in high grade condition and would be worth close to the price I paid for all of them.
But when I got home & took the #50 out of it's protective cover I found that it had a small 1.5" cut/slit on the cover! It's a clean cut; the edges go together perfectly & when in it's sleeve & pressed flat it's almost impossible to see at a first look (it's actually in the middle of the back of Spider-Man's right arm).

How would this affect the grade if I send it in to CGC or another comic grading company?
Is it worth having it repaired?

The Amazing Spider-Man #51 looks Near Mint - Mint with no issues & the rest all appear high grade comics.

Also, there was a Fantastic Four #300 that has a signature that I'm hoping is Stan lee's signature (Here is one of his that resembles it to me: https://www.ebay.com/itm/Beautiful-...485021?hash=item3651bba15d:g:oukAAOSwMoZcbsbN ) - does it look like Stan lee's to anyone here (who's not looking at it with wishful thinking!).

As always I thank you & I appreciate any help you can give me.



THESE ARE THE OTHER SPIDER-MAN COMICS I GOT FOR THE $1,000 - DID I MAKE A GOOD DEAL??

 

It looks like Stan's sig, which varies some from sig to sig. If authentic, should be worth a bit of a premium (he signed a lot).

 

Thanks I'm hoping it's him to help make up a little what the cut in the Spider-Man cover will lose.

 

Unfortunately, the premium the signature adds seems proportional to the underlying value and #300 is not worth a lot (single digit). So the premium likely well under $100 based on similars.

 

Well outside of my realm of knowledge but those are really cool! I think there is a rather large comic book forum out there on the web hosted by one of the Third Party Grading Companies with a lot of fanatic comic book enthusiasts -- you might want to check it out.

 

I sold the Amazing Spiderman comics for $1,300 - it was a 30% profit within a week + I still have the other comics (to read while in line early waiting for my local thrift store to open!)
