Hello I just got the grades back on my first tag submission! I'm fairly happy with the grades except for my Dawn SIR from Phantasmal Flames. The card is absolutely mint I didn't get dinged for any edge, surface or corner defects but received an 8.5 grade due to centering 60/40. I checked the centering before sending it and it was 53/47. I used a physical centering tool not one of the online ones. Even visually looking at the card on the dig report shows nearly perfect centering to the naked eye. Is there any way to contact Tag prior to them shipping it back to have the grade reviewed?
