Actually i had a grimer just like that years ago that was a fail print. But I haven't seen my pokemon cards in years though since i stopped playing with them when i was 10. I think their somewhere in my closet though but fat chance I'll be able to find them now. The card printer must have had a malfunction that day that caused the misprint. So i guess you could say that it's a rarity. At this point in time it may be one of a kind since some where probably thrown away at the time as defects and others just couldn't stand the test of time. Congrats.
