"I'm searching for an answer to a bit of baseball card mystery. I have a set of the 1989 Donruss Baseball's Best. The whole set itself is not factory sealed anymore but each individual pack of cards in the set is still sealed.

I noticed something some time ago that I've not seen before with this set and I have seen a few of these sets over the years. The pack that has the Gary Sheffield showing on top, also has Gary Sheffield on the bottom of the pack, showing the back of the card.

Naturally, I can't help but wonder: Is the whole pack full of nothing but Gary Sheffield cards? I've been looking and looking and have not seen another one like it nor have I found anyone else that has seen that. So, that is my question: Do you know anything about this or have you seen anything similar with this set? So far I've resisted the urge to open the pack but man is it tough. Any suggestions?"

If you don't feel comfortable leaving a comment, email me and I'll make sure your answer gets to Grant.
