2000 Upper Deck Black Diamond Baseball Forum

These are just a couple of questions especially for anyone with cards from the Upper Deck 2000 Black Diamond Set.  The front of these cards have a metallic tint to them, especially if you rotate them away from you slightly and view them a bit from the bottom.

I have three (3) cards of #78 Edgar Martinez of the Mariners, and noticed that two of these look metallic blue(-ish), but the other is distinctly different and I would say it is metallic green(-ish).  

I am wondering:

a) does anyone else see this in their cards from this set, especially maybe with Mariners?  i have doubles (or triples, quads, etc.) of several other cards, but see no variations there.

b) would we consider this normal printing variation, or an actual variant within the database?

Appreciate any info/guidance/opinions you may have.  Thanks!
