Does anyone know of a reason the cards in the Four on Four Fabrics set do not have a card number listed?  The cards do come with a COA insert with them that list the number.  For example, the card that has 4 Portland Trail Blazers and 4 Utah Jazz players on the front/back has a COA with it that says the card number is FF-PORUTA.  The only reason I can think of is the COA card is not part of the card itself.  But I thought I'd check with everyone here before just adding in a card number for the ones I have.

Thanks for the feedback!

Anyone that has just the card without the COA won't be looking for a card number. The number can be added to Note2 though.
