I went to buy an Ace 10 Pikachu with grey felt hat from someone, on inspection I noticed it was in a penny sleeve inside the slab, is this a big red flag for a fake? The QR code was off centre as well. I didn’t get chance to take a photo of it. EDIT: when I scanned the QR code it took me to the ace grading site but didn’t load a picture of the card.
