The Original PMGs will always be iconic and highly valued among collectors.
I'm not too sure if this is gonna hold true for the Retro PMGs though, especially with the release of the Prizm product. I've said it before, years down the road, Gold Prizms will be more valued and more sought after then the Retro PMG Greens. I mean, just take a look at those Lebrons for example, Panini has arguably just made Lebrons BEST card in his HEAT uniform, and they did it without needing his signature. When it comes to Lebron, I think a similar thing is gonna happen like it did with Jordan in the 90s. Although Upper Deck had his license for signatures, most of Jordans best cards come from Fleer and their inserts.
