This is a link to a post I placed on the baseball forum. Perhaps someone here can give me an answer, since this is the most awesome forum on Beckett

If I remember correctly, I think the one up top is a Grey Back and the bottom one a White Back.
Just variations is basically all it is, but I think the Greys may be worth $.50 more or something small.

I believe that the SP's are printed like that

They look different to me
SPs

Non-SPs

The common Sp's go by the numbers, 426-500 and 586-720 are all common sp's, then there are the Variation sp's that go by the coloring combinations on the front of the card, or by an intentional error on the back.

and yes, you are right about the darker back, The short printed cards have darker backs than the non-SP cards.

Hope that helps.
