A rare authentic GAI certed Mantle?
 

I am partial to the BB Immortals set signed so I got excited when this one popped up and then saw the GAI Baker cert but ... the autograph looks textbook perfect Mantle (unless I'm losing it at the ripe old age of 42).

Were these guys good at one point before certing all the crap forgeries?

Card and cert (which does not appear to be found entering it into their database) in question:

If someone slipped up and submitted an authentic Mantle autograph, they authenticated it just like all of the bad ones submitted that they authenticated.

This one is good whether they authenticated it or not!

Having their hologram on it does not help if reselling but if just collecting, it is authentic.
