Been wanting a nice Frank Robinson Rookie, and this one looked pretty nice for the grade. But it was rejected by eBay Authentication, and I was automatically and immediately refunded.
Seemed like this one would pass in routine fashion. I can't imagine what SGC might have missed, and of course you never get any kind of explanation or specifics from them.
Does anyone see a red flag or problem that caused this slabbed card to fail?
