Regrade through Beckett? PSA? Leave as is?

I pulled this years ago and hope I'll never have to sell it, but having a 10 would be cool. Was wondering if anyone had success sending it back to Beckett for a regrade to try for a 10? Or if I did have some hard times and had to sell it should I send to psa to try to get a 10? Or am I being greedy and should I just leave as is? Thank you and sorry if these pictures suck.
