I am need of some help, I purchased the 1985-86 Mario Lemieux OPC rookie graded a GAI 4.5. I have s for n some very recent posts about possible fakes, to make matters worse I got on EBay where I bought the card to compare mine to a PSA graded card. I came across the same card the was sold to me from the same seller, now if I didn’t have doubts I have them now. I need to know what is the likely hood that this card is real? Any help would be greatly appreciated, thank you in advance!
