If you buy it for 100k then I will officially dub it "Most uninformed purchase ever" - Currently someone else holds that title so please don't try to top them.
It is not worth 100k no matter which way you look at it. I think the 50k price range is just about right since it is the only PSA 9 out there and its rarity.
People need to stop, think, research, and then do more research about card pricing. Just because something is listed for 1 million dollars doesn't mean it is worth even near that amount.

There is a reason that we have a "What is it worth" thread on this forum.
