I just got one today, and it looked perfectly normal, except for the back of the card. The art on the back of the card was upside down. Either that, or the front is upside-down. Is it a fake? If not, how much is it worth?
ive never heard of this happeneing but that is a very strange occurance. my friend opened a pack today and one of the cards was upside down in his pack. it was funny.
I suggest to show that to some TCG store owner. Although recently there aren't many. My advice is to check the other details. Such as comparing it to another Mew card that's normal. I once had a Machop that didn't have a tail.
