Unique grading conundrum, need advice
I have a rare valuable card from the 50s that regardless would be graded as a 1, 1.5 at best. Anyways an issue is some owner of this card along the way wrote the players name on the front marking the card. I sent the card to SGC to be graded thinking it would either be a 1 or Authentic grade however they are sending it back to me because they can not grade it. I reached out to support asking if it was because the mark, questions of authenticity, or just too poor of condition and they said the reason was they can not do after market autos, which i knew but this is clearly not his auto. Anyways I think i am going to try to send it to PSA next to see if they can authenticate. Has anyone been in a similar position to as this before? Am I kind of screwed getting the card authenticated because someone wrote the players name on the card at some point?
