Question about BGS grading 'authentic'
I obtained a card in a trade. It is a Chris Johnson Contenders rookie auto. It is slabbed by BGS and the auto is graded a 10. But instead of a card grade, it says 'Authentic'. I never thought anything of it but has been told that it happens because the card is damaged. I looked over the card myself, the best I could and the card doesn't appear to have any noticeable damage.
So why do cards get labeled like this and how does that affect the value of the card?
Bury me alive, bury me with pride
Bury me with berries, that forbidden fruit and cherry wine
Thank you berry much, but tonight's my night and I'm Barry Bonds
Swingin' for the fences, barbaric Kendrick in idle time
