I mean what are the chances of the printer running out of ink like that and printing in blue instead of green. Maybe not worth $500 but I could see paying $100 for it.
The only other misprint I have ever seen is my copy illusion of gaia which i received off of ebay in a lot of games. There must of been some malfunction at the factory because the label was completely missing from the cart. I have pics if anyone is interested.
