Compare 2 '56 Mays cards

Dave is correct. Top Mays is gray back, bottom is white back. A good little way I can tell is by looking at the front of the 56 Cards. Gray Backs always have better front color, white backs look more dull. Mays white back is more scarce.

As far as grades, with the bottom edge wear I'm seeing on the back of the top card, I'm thinking a 5 - 5.5.
Bottom card about the same due to multiple touched corners. Both are worth grading, IMO. Might even get a 6.5 on one of them.

The bottom/white back card sold (not to me) earlier this week for $170. I was watching, but missed the deadline.

The top/gray back card is one I am considering buying. I think it's priced too high so I am taking a wait and see approach. Possibly trying to combine it with a similarly worn '56 Aaron. It's a white back, but at card #31, the white back isn't rare. I'm also a little worried about what looks like the surface scratch in the umpire's back and a small one across the red bill of his cap. And would the centering be a grade issue? I'm thinking at a lower grade it wouldn't matter, but appreciate input.

On the gray/white backs... I never understood why the white backs get such a premium typically from 101 - 180, but the gray backs don't get that premium in the #s below 100?
