Who would have thought that cards with a bunch of gross little kids on them would end up becoming so valuable? While some contain pretty standard levels of grossness, such as boogers and farting, some are downright freaky. We mean it! Doesn't anybody remember the kid eating a sardine and unzipping his skin to reveal robotics underneath? Or the one made out of metal springs who is in a straightjacket?
Bizarrely enough, these guys are worth thousands now. So, if you were someone who enjoyed such things, now would be the time to sell. An original 'Adam Bomb' could rake in around $4,000, while any of the Japanese versions of the cards will definitely sell for more than $1,500. A full set of just regular, non-original cards sells for around $700, so start setting up an eBay account.
