Here is what I know...
Officially released red carded with Holofoil Sticker:
Ben (Obi-Wan) Kenobi
Yeah, those are the only three legitimate, standard release orange carded holo stickered figures there. Of course, it goes without saying that you really have to watch out for fakes with these too (any
stickered orange card). Pretty simple to peel the foil sticker off a green card and slap it on an orange card. Though to the observant people, you can probably find some fairly noticeable telltale signs that this is what happened - like stressing (stress lines) in the sticker, or one of it's corners being a little dinged from where the lift originated.
But there are a few of those prototype samples floating around as well, as listed above - but they weren't standard releases as far as anything that I've heard. As for the regular three, I managed to snag the Stormtrooper and Yoda orange card foils at retail, but never saw the last one - Ben. Oh well, maybe later...
