I was going through my recent Steve Largent additions and adding the missing cards to my TCDB collection and I noticed after I scanned in three parallels from the 2005 Donruss Elite Back to the Future insert that the serial numbers are not printed the same way. The green parallel that is #/1000 has the top of the serial numbers nearest to the right border while the Blue #/500 and Red #/250 have the bottom of the serial numbers facing the right border.
I took a look at other player’s cards in the insert set and they are all serial numbered like mine, with the green parallels having their serial numbers in a different direction than the blue and red parallels.
I think the only reason I noticed this is because of my OCD and need for order. Damn you Donruss for messing with me and flipping the card sheets when printing the serial numbers.
