Their website is sgccard.com and they say on the site "The Industry's Most Trusted Grading and Authentication Service."
I see a few balls that I like with that SGC coa. I have seen them at some local shows around the cincinnati area, but I was kinda turned off because I was looking at a fake mantle ball on one of the vendors stands. I said Im pretty sure this is a fake mantle ball and the vendor said well that guy over their just certified it. I turned around and it was an SGC stand..
I know there will always be mistakes but I dont see them much and dont see much of their COA's on baseballs; mainly cards.
Any advice?
