Auto Authentication ?'s, advice

jas0526

I recently purchased an autographed 1993 SP Jeter card and want to have the auto authenticated. To preface my question, I usually would have no issue sending this into PSA for authentication, but I love the way this particular card issue looks in a GAI slab. This card will not be resold, it's just for my PC. Does anyone know if GAI will slab a card w/o a grade, just with 'Authentic' like PSA does? I cannot locate information on their site regarding this. Any help/comments are appreciated. Thanks guys
