I would not be surprised to find out that most of the Red Borders just do not exist. They're something I don't go crazy looking for, but I barely ever see a Red for anyone I collect for 2010 Topps (and there's at least 50 cards in that set that are in my PCs).
Those red border cards are surprisingly hard to find. I've only seen one seller sell them of Gomes in the past few years, and the 2012 parallel (orange border) seems equally rare. Only seen something like 4-5 of them, and all right when the sets came out. I'm not sure why this is---maybe as [MENTION=6243]jimfalbo21[/MENTION] suggested, they're in sealed factory sets---but I wouldn't be surprised if all red border cards purported to exist actually do. Keep in mind that while it's easy for cards on a checklist to actually not exist, it's also easy for cards (especially ones not worth more than a dollar or two) to not get listed for extreme lengths of time.
