> How many of these exist?

90 http://en.wikipedia.org/wiki/Nintendo_World_Championships#Ca...

There was a guy on reddit who was actually a winner in the 18+ category who still has his with its label

If this one is worth 90k then his must be double that

This one is not worth 90k. It got published on multiple news website and now there's ton of fake bid on it. In good condition it's worth 6k but I've never seen one in this bad shape, it's probably worth much less. The gold one is worth way more, about 20k in good condition.

But bids can be done by anybody. Without any confirmation. So I'm still not sure about price.
