I have nearly a complete set of these cards. As I was going through them I discovered 1 card that is lacking the Upper Deck Foil Logo that is stamped into the card. I have a few others that wave or are wearing away and I can see where the logo is indented into the card. However, This card I have has no indent, I am thinking that this card did not get "stamped" logo placed onto it. Does this increase the value of these otherwise worthless cards? Where can I take it to get a better Idea if it is actually an error card?
