The backs of all three cards are identical. If I showed you one I've shown them all. The photo on all three is the same. The logo's the same. The squares are the same. The swatches have no discernible difference. All that Upper Deck has done is add the words "Silver" or "Gold" and "Limited" and changed the color of the serial numbers. And as long as I'm complaining, there were only 75 more of the first one made and it is serial numbered. Why doesn't it say "Bronze Limited"?
There comes a point where I am inclined to just buy one of these cards, if possible the "rarer" one, and leave the others alone. I guess this line of thinking opens a can of worms. What is collecting all about, etc.? Why collect any cards at all, blah, blah, blah but I guess all of us have drawn lines in the proverbial sand when it comes to our collecting habits/philosophies. I'd love to hear what you guys and gals think.
