1 dozen Casino strip used playing cards

After the cards are used in the casinos--generally for less than one shift--they are "retired". 

 Each casino shift boss marks the cards in a different way so that they can't be brought back into play in the casino (security reasons). 

MOST CARDS JUST HAVE A VERY SMALL CORNER THAT WAS CLIPPED OFF

 BUT SOMETIMES THEY USE MARKERS ON THEM FOR SECURITY REASONS.

OTHERWISE THEY ARE LIKE NEW WITH THE CASINO LOGO
