At a certain point, cards are no longer in their preferred "mint" or nearly new condition. Casinos look to sell these used decks of cards to the general public, but before doing so they'll either burn the corners of the cards or puncture a tiny hole through them in order to prevent cheating. The cards being sold to the public look identical to the ones being used on the casino floor, so a tiny hole or a burnt corner will prevent any confusion between the cards sold to the public and the newer cards still being used at the casino.
