Repro cards are getting scary good. I'm not sure if they can fool the graders yet, but it seems possible at some point. Wasn't there a big ruckus several years ago because someone slipped a faked vinyl cape Jawa past AFA? @comicwiz @Buzzetta? I may be wrong, but that tickles my brain for some reason. I am generally wary of carded figs for reasons given above, but also because of repros, unless I can verify that they're from an original owner collection. And even then, I don't like to pay much of a premium for them. I like carded stuff, I think it's super cool to look at, but I wouldn't put more into them than I could afford to lose it they eventually fell apart, or I guess the new concern, turned out to be faked!
As for the market, I'm sure others can weigh in, I haven't dealt much in Star Wars for a very long time.
