Craig WI also played Q & A with the seller 
Q: "Hi. Your description of this Plank card says it's a professionally graded SGC 9. Is there some reason it's not in an SGC holder? Thank You."
A: "Good question. The information given base on my research. I do not collect them, so I don't know why it not SGC holder. Thank you"
