After the cards are used in the casinos--generally for less than one shift. The cards are then sent to the prison in Nevada where the "residents" sort, and reseal the decks. We buy these decks sealed and we're not responsible for a missing or duplicate card on sealed decks. THESE CARDS COME IN AN OPENED BOX AND ARE UNMARKED AND UNCANCELLED. OTHERWISE THEY ARE LIKE NEW WITH THE CASINO LOGO. **These may or may not have Jokers as casinos do not use them for table games.** If you are running an important tournament or high stakes game, you should consider KEM, COPAG or ROYAL plastic playing cards or brand new decks of plastic coated playing cards.
