Need to Grade a Michael Jordan Rookie Card

[Jerry25]

I bought a Michael Jordan rookie card that is graded by USA as a 10- I have never heard of them, but I was able to inspect the card for myself and used a jewelers loop to verify authenticity. I'm thinking I'm going to break it out and send to either PSA or Beckett. I'm hoping for a 9, but understand that is a stretch. Thoughts on what I should do - who should I submit to if any? I'm trying to maximize value and probably going to sell since I already have a different Jordan rookie that's better than this one
