RobIn the piedmont wagner post Scott mentioned a rebacked Matty that was graded PSA 7 then regraded by SGC as a 50.
1)If it wasn't for the "impossible" back (lets say it was rebacked with a brown hindu back instead of red), how could it have been discovered that it was rebacked? Why didn't the grading companies discover it, and how can other collectors watch their own back when buying raw to avoid buying a professionally-rebacked card?
thanks,
Rob
