Just had these $3-$4.00 dollar cards delivered the other day and I immediately noticed the different color variations on the back.

Of all the 52 Topps cards I own, none are as light as this, Joe Muir card.

All my cards, for the most part look like the Sheldon Jones card, maybe a tad lighter but that is all.

And although I don't have any cards in the Gray Backs number range, I really think, if I did, it would be difficult to distinguish them apart from the others I own.

Can anyone explain this severe color variation, especially since both these cards are so close together numerically?
