Card Identification Forum

While going thru my Phillies, I noticed a distinct difference in the card fronts on 2001 Leaf Certified Materials.  Note gray stripe across the top and bottom of the one on the right.  Stripes are very similar to those on the card backs.  The one on the left has chrome stripes top and bottom.  I have Rolen and Burrell, also with gray stripes on front.  ???  Thanks for any help - could find no help on the net!

I'm not a collector of baseball stuff, stick to hockey but I would say something as far back as 2001 should have some kind of info on a parallel that is grey stripe vs chrome stripe. If not they could be simply just misprints that never got the chrome added, this sounds like a good case for captkirk or bobzcards possibly, there is one member on here that speacializes in error and variation cards.
