I'm almost embarrassed to ask. I love the set so much that I should know already. However, I am not one to go for "master sets" so I am not informed on the variations. I am upgrading some cards right now and have two questions:

(I did try to do some research but got some conflicting info, so I figured I would ask some collectors who might know better)

What is the "white back vs. grey back" issue? Is one more expensive, and why?

Secondly, some team cards have the year number on the front. For example, I have a Braves team card with the year and a white back. Is that a good thing or pretty common?

Thank you in advance!
