your opinion of this 52 Mantle
 

This card has the missing blue pixel, top corner overlap, uneven lines around Yankee logo, border around Mantle's name not as smooth as type 1, and on the back, stiches on baseball point right, and T in right and S in DiMaggio align.
your opinion and why please.

It looks 100% fake to me.

The corner wear looks both too regular, and just "wrong" A hard thing to explain. Some degree or regular corner wear is usual, and another point against other cards is uneven corner wear, so I've always been against that as a stand alone point for or against.

The interior cardboard on 52s should match the back. Here we have a card with a dark back showing light cardstock where the creases break the surface.

The color and lack of definition on the edges of things also looks wrong.

So overall, I'd expect it to be fake.

Centering is too good along with the corners being rounded on purpose. Chances of this being real are slim to none.

Good try but no good.

Agree with the above response for reasons.
