LeBron James rookie card sells for record $5.2 million (espn.com)
Mike Trout rookie card sells for record $3.93M at auction - CBSSports.com
Some big name rookie cards have recently sold for a lot of money, so now people are going crazy trying to get them because they think it will make them rich. It actually predates the Pokemon stuff and you have stuff like people camping out trucks and having their employee friends hide product.
People are literally buying all the product up as soon as they are taken off the truck. Like one or two people buying out entire stores. This is also happening because of safety reasons
Not unless the cards are selling for big money.
according to tcgplayer, the new set's full art Lightning cards are selling for 250 apiece, more if they're foil. I dunno how they'd get more expensive than that for cards still in print.
