Hello! I am a newbie to pokemon cards. I have bought quite a few packs and have become quite familiar with pokemon TCG, but I still cant figure out something. It seems that on all of my cards (most of them) there are white marks or chips on the card around the edges or along the sides of the card on the back. Is that normal? It seems that sometimes when I open a booster pack there are white marks on the cards even right out of the pack. Also, on this forum I have seen people refer to Walmart as Wal-fart, why is that? Thanks.
