500 hr club ball

For my education, could someone explain what are the clear indicators of a fake Mantle auto? The scans are poor but posters seem to be very firm that the sig is fake. I've been trying to compare it to my single signed balls which are 100% real since I saw him sign them with my own eyes and I'm having difficulty. Thanks for any info.
