savemoneycards

I have a 1955 topps Hank Aaron #47 psa 6 I thought I should of had an easy 7 but no luck. I want to make money on this card so should I go to the big card show comming up and get it graded by sgc to see if they would give me a higher grade? some people tell me they are a little better on giving good grades to vintage cards. Just wanted some info thanks
