Card grading, previously experiences?

[bomber5]

I want to have my leaf. 2012 muhamme Ali auto graded, its a high end card in my opinion and I've never had a card graded. I'm scared to send it off.. And never get it back! has anyone had a problem that I'm scared may happen? Also experiences , Beckett? PSA? SGC? Card grading Australia?
