They look like they are printing plates to me, card companies do this as a 1 of 1 type of thing, I'm guessing you may know all this already but will continue in case you do not. There are usually four different colors, Yellow, Black, Magenta and Cyan and some do fronts and backs just like you have. I'd say you pulled magenta and black. As for if they are worth anything that would take a bit of research online and you should be able to find the info you are looking for. I see there is nothing listed on the DB for that set pertaining to printing plates and I have zero knowledge about football stuff. This is about the best I can do to help, sorry. =)
