They are the exact same CC jersey from the UD Divisional Artifacts series with one notable exception: the top card is numbered /199, the one on the bottom has the rough spot where a serial number would go but does not carry a number.
Which then leads to a bothersome question if you place a lot of value on serial numbered cards: if there are print overruns, whether intentional or unintentional, that mean a card numbered to /199 is actually, say, unofficially to /400, how does this change the value of the card, if at all? And if not, why even place a premium on these cards? If a certain company were to do this intentionally it'd be pretty easy. Not with 1/1s to be sure, but with /25 or /50 cards. Heck, Salvador Dalí was infamous for signing running off 1000 prints of a given painting, numbering the series /100, then signing ten 1/100, ten 2/100 and so on. He he could do it, why not card companies?
That said, don't forget to check out the 2010 t206 group break over here. Lots of great teams available.
Have a good one everybody and goodnight Pumpsie Green, wherever you are!
